By Jeff Risdon Updated 4/14/10 1. Russell Okung, Oklahoma State. 6?5?, 307 pounds Positives: Very impressive physical specimen with long, powerful arms. Very heavy initial punch and strong hands to lock up defenders. Uses his feet and shoulders very well in all facets of blocking--stays square, keeps balance, gets and maintains leverage. Decent base strength when he stays low. Tremendous upper body strength and he understands how to deploy it. Good anticipation, sees the rush and makes correct pre-snap adjustments. Intense competitor that respects the game and his responsibility as a leader and great talent. Negatives: Inconsistent technique; unexpectedly lunges and grabs at times and will let his hands get way too far outside. Gets upright when running and searching for targets at the second level. Appears to dwell on his mistakes--once beaten, he will get less aggressive and appears less confident. Not as aggressive a run blocker as some teams/coaches prefer. NFL Comparison: Walter Jones, Chris Samuels the younger Forecast: Will be the first tackle taken and will not fall out of the top 5 overall picks. 2. Anthony Davis, Rutgers. 6?5?, 323 pounds. Positives: Has all the physical tools to be a perennial Pro Bowler--long arms, athletic with quick feet, great natural base strength. Very comfortable, fluid natural athlete. Flashes nastiness and can play with violent tenacity. Gets very good leverage and sustains his knee bend. Quickly extends arms and locks with strength. Plays to the whistle. Adept at sealing the edge and creating and sustaining lanes. Great leg drive in run blocking and has good feet overall. Tenacious downfield blocker that can really get out and lead the charge. Has played guard and has the ability to play any OL spot except center. Negatives: Attitude and maturity are questionable. Weight has fluctuated throughout his career. Played to the level of competition, often getting embarrassed by lesser talents. Gets caught flat-footed, kick step needs improvement. Coaches and teammates have not exactly rushed to his defense in the face of criticism. Skipped his own pro day and has shown a general disregard for responsibility and taking advantage of opportunity. NFL Comparison: At his best, Ryan Clady; other times, George Foster. Forecast: Big-time boom/bust talent with maturity issues but some very impressive game tape and physical attributes. Upside is too great for him to fall out of the top 20 picks. Could be the best tackle in this draft, could just as easily be out of the league in 3 years. 3. Charles Brown, USC. 6?6?, 303 pounds. Positives: Light on his feet with tremendous lateral agility for the position. Long arms but also blessed with extremely big hands that really stand out. Quick off the snap with good pad level and natural knee bend. Consistently improved his punch and at sustaining his arm extension and strength. 3-year starter in a pro-style offense at a major program. Has a good feel for the position despite being a converted TE. Great kick step outside. Well-respected by his teammates and opponents, who voted him the Pac-10 lineman of the year. Negatives: Lacks sand in the pants. Played in the 290?s at USC, which is extremely light for NFL tackles. Has gained bulk but it appeared to slow him down. Not a powerful run blocker, more of a place-holder. Had some issues pass protecting inside and handling bigger tackles on twists and stunts. Not a great recovery blocker. Strictly a left tackle, which makes some evaluators (not me) nervous. NFL Comparison: D?Brickashaw Ferguson, Duane Brown Forecast: 1st round, anywhere from 8-25, and should be an ideal LT candidate for a zone-blocking team. 4. Bryan Bulaga, Iowa. 6?6?, 314 pounds Positives: Well-seasoned tackle with a good balance between power and finesse. Excellent mirror blocker against 5-technique pass rushers (see Orange Bowl). Very powerful initial hand punch, good hand placement and arm strength at full extension. Finds targets at the second level in run blocking and can engage with leverage and balance. Smart player with good anticipation. Comes from a program noted for churning out quality, well-coached linemen. Negatives: Had real trouble with speed rushers lined up more than a step outside his left shoulder (see Michigan game & Brandon Graham). Has even more trouble picking up delayed rushes or blitzes from the second level, particularly once the TE cleared (see Ohio State and Wisconsin games). Lacks great base strength, though he compensates by consistently getting good leverage. Not a road grader and doesn?t play nasty. Battled a fatigue/thyroid disorder that caused him to miss 3 games, and missed several games early in his career due to injury. NFL Comparison: Jeff Backus Forecast: Lower-ceiling/higher-floor prospect than any of the others in the upper realm, which will repel some teams but attract others. Will go in the top 15 overall and will almost certainly be a decent-but-not-outstanding starter for a decade. 5. Rodger Saffold, Indiana. 6?4.5?, 316 pounds. Positives: 4-year starter in the Big Ten that steadily learned and improved. Solid athlete with great feet and balance. Good hips, decent lateral agility and the ability to move quickly in tight spaces. Sets up quickly and does a great job squaring up his target. Stays balanced and keeps leverage and good pad level in run blocking. Very good on the move in run blocking, ideal for a zone blocking scheme. Steadily improved his mirror skills and sustaining good angles in pass protect. Well-respected by his opponents. Negatives: Not overly physical or aggressive. Can get caught guessing by more versatile pass rushers. Will get too upright in pass protection at times and stops moving his feet when he does so. Has battled a back injury. Not as long or strong as teams ideally want in a LT. Some coaches will not appreciate his calmness or cerebral demeanor. Some evaluators believe he projects better at guard. NFL Comparison: Sam Baker, Chris Williams Forecast: A very strong postseason has elevated the experienced Saffold from the middle rounds to the top 40 overall. Could be a real gem. 6. Trent Williams, Oklahoma Overrated athlete with great measurables but he needs a lot of refinement. Aggressive, powerful run blocker with requisite snarl that really seals the edge well. Does a good job engulfing defenders that approach him squarely, and he?s adept at recovery blocking if he loses the first battle on a play. Inconsistent with his hands and feet--at times he is textbook, at times he is wide, unbalanced, and sloppy. Plays too high too often. Some have questioned his motivation and work ethic. Was an elite athlete early on and effectively coasted on it for a long time. Played better at RT and that?s where he belongs in the NFL. Has great upside for the right coach and environment and will be drafted as such; surefire 1st rounder and likely top 10 overall pick. 7. Kyle Calloway, Iowa Prototypical corn-fed, heavy-legged mauling RT. Fundamentally sound and has a good football IQ. Probably the most consistently tough and effective run blocker in this draft. Has some experience playing LT but has always struggled with quicker (not necessarily faster) and smaller defenders. Limited athletically with short arms for his size and his footwork lacks fluidity. Not as nasty as you would expect. Is already as good as he?s ever likely to be, but is ready to play at RT right away and needs little coaching. 3rd-4th rounder. 8. Jared Veldheer, Hillsdale Small-school giant (6?8?, 312) with incredibly wide shoulders and good upper-body strength that consistently dominated in the best D-II conference. Great athleticism and good balance for a taller player. Not overly aggressive or tenacious and can be too passive in run blocking. Needs some work on his feet and initial punch. Lots of developmental upside but needs roughening and seasoning. 2nd round prospect that favorably compares to Sebastian Vollmer last year. 9. Jason Fox, Miami FL High-effort swing tackle with good measurables and strength. 4-year starter at a major program that had lots of adversity during his tenure and he exuded leadership in time of need. Not an explosive athlete but is fairly technically sound. Seals the edge nicely on runs and fares well in space for a taller (6?7.5?) prospect. Dogged fighter who never quits and inspires teammates. Coming off a leg injury that inhibited workout season, and he has missed games in the past with minor ailments. Sort of a right tackle in a left tackle body. 3rd-4th rounder. 10. Bruce Campbell, Maryland His workout numbers are off the charts, but game film reveals a technically deficient, uninstinctive, inexperienced reach-and-grabber. Did show flashes of being a dominant outside wall, and everything that is wrong with him is coachable. He comes across as coachable and eager to learn. Has the physical potential to be great, but it?s not going to happen quickly. Will be drafted in the 1st or very early 2nd round, which might look fine in 5 years but will likely appear a huge mistake until at least 2012. 11. Tony Washington, Abilene Christian Talent-wise he belongs well above this ranking, but he has some character concerns (primarily from earlier in life, Google him) that will repulse some. Very impressive athlete with great measurables and fluidity that works very hard at getting better. Gets upright too quickly and his footwork and hand placement need refinement, but he?s very coachable and eager to please. Needs a strong coach and supportive system but could blossom into a very good starting LT for a team willing to take the chance and the time. 2nd round talent that will almost certainly slide to at least the 5th based on his past. 12. Kevin Haslam, Rutgers Doesn?t show any real great skills, but he has a consistent portfolio of being an effective all-around tackle with no real deficiencies. Smart, hard-working, technically sound, can get nasty if needed; an ideal #3 tackle that could play a long time for a coach/team that appreciates him. 13. Selvish Capers, West Virginia Lightweighted finesse tackle with great quickness and agility, but really lacks base bulk and requisite upper body strength. Intelligent, dedicated, try-hard leader that has some appeal to zone blocking systems, but he?ll require TE help in pass protect. 5th-6th round. 14. Ed Wang, Virginia Tech Unpolished athlete with great work ethic and athleticism that could be a very pleasant mid-round surprise if he learns better technique and gets nastier. Quick learner that could thrive from positional stability. 15. Tyler Eastman, Maine Rising late-rounder with a quick learning curve and impressive athleticism. Recently lost 15 pounds but added upper-body strength, indicating he could blossom with more attention. Only started for 2 years at the FCS level and his feet aren?t great, but he has some Phil Loadholt to him. 6th-7th rounder with promise. 16. Ciron Black, LSU Thickly built, soft-bodied plodder that is a much better guard prospect, does not have the agility or fundamentals to play outside. 4th-5th rounder as a guard that can play tackle in an emergency. 17. J?Marcus Webb, West Texas A&M Big-footed Texas transfer with questionable work ethic and attitude but great power and surprising agility for a 6?8?, 337 pounder. A poor man?s Bruce Campbell that some team might take a late 7th-round flier on, but more likely a UDFA/practice squad developmental stash with major athletic intrigue and upside if he takes to coaching. 18. Adam Ulatoski, Texas Over-aged, overhyped throwback-type with poor feet and a finesse style in a power body. Likeable worker with strong experience but athletically limited and stiff. 6th-7th rounder that will have to make it on special teams. 19. Chris Scott, Tennessee Soft-bodied G/T tweener with surprising quickness and good fight. Needs work on pad level and technique and will never be much of an athlete, but there are some tools here to be developed. 7th round/UDFA 20. Will Barker, Virginia Giant, late-blooming guard/tackle tweener that lacks athleticism and doesn?t play as strong as he looks. 5th-6th round pick as a utility/swing lineman for a power-oriented team. Others Levi Horn, Montana: Converted TE with good length and decent feet but needs serious weight room work. Has gained momentum based on his workouts and obvious work ethic and desire. Good late-round developmental sleeper. Sam Young, Notre Dame: Tall, lanky, and unable to bend at the waist or generate much power with his lower body. Very mediocre pass rushers got into and under his pads all year, and then the really good ones at the Senior Bowl dominated him. Too tall to play guard, will have to stick as a backup swing tackle, which is typically 7th round/UDFA territory. Vlad Ducasse, UMass: He?s a much better prospect guard and will be listed with that grouping. If you must know, I would slot him somewhere between 11-15 in this list as a tackle prospect. Will likely be drafted in the 2nd-3rd round and could become a very good NFL guard. Thomas Welch, Vanderbilt Similar to the problems that plague Sam Young, except Young is a better run blocker. Dennis Landolt, Penn State: Could stick as a reserve lineman, good RT/G run blocker with plodding feet and short arms. Derek Hardman, Eastern Kentucky: I only saw one game film so any evaluation is limited. Good size, decent feet, but a big jump in level of competition and he looks to need to add at least 10 pounds of lower body bulk. Chris Marinelli, Stanford: Exposed during postseason games for his egregious lack of strength and inconsistent technique. May get drafted on reputation and impressive persona/leadership, could be effective inside with more bulk. Chris Campbell, Eastern Illinois: Stood out at Texas vs. Nation practices with his athleticism and size. Very raw project priority UDFA that will likely stick on a practice squad for a year. Kyle Jolly, North Carolina: College tackle best suited as a backup interior OL in the NFL due to lack of quickness but strong short-area skills. Could surprise some as a right tackle under the right coaching.
