Bill Belichick is ranked as the best coach in the NFL, according to a poll of 30 league insiders.

Pete Carroll and Sean Payton are ranked second and third and are also in their first tier.

"The most important thing to me is the ability to control the offense, the defense and the special teams," a GM said in describing the ideal coach. "You can change and you can coach multiple things and you have the ability to teach almost every position group. Then you can lose any coach you want and replace from within because the head coach is the talent. Belichick is the ultimate model of that."

Belichick commmanded a 1 vote on 28 of 30 ballots.

In Tier 2 are Andy Reid at No. 4, Tom Coughlin at No. 5, Mike McCarthy and Mike Tomlin at No. 6, Jim Harbaugh at No. 8, John Harbaugh at No. 9, John Fox at No. 10 , Jeff Fisher at No. 11, Chip Kelly at No. 12, Bruce Arians at No. 13, Lovie Smith at No. 14 and Mavin Lewis at No. 15.

Tier 3 is led by Chuck Pagano At No. 16, followed by Rex Ryan (17), Mike Smith (18), Gus Bradley (19), Ken Whisenhunt (20), Mike McCoy (20), Marc Trestman (22) and Ron Rivera (23).

Tier 4 features Mike Zimmer (24), Jay Gruden (25), Bill O'Brien (26), Jim Caldwell (27), Doug Marrone (28), Joe Philbin (29), Jason Garrett (30), Mike Pettine (31) and Bruce Allen (32).

The Jacksonville Jaguars are attempting to avoid repeating the same mistakes they made with Blaine Gabbert as they bring along Blake Bortles.

“This fan base saw a quarterback get thrown to the wolves,” offensive coordinator Jedd Fisch told me, referring to Gabbert. “We don’t need to force it. We never thought when we drafted [Bortles] we were taking him to play now. But nothing is set in stone. We’re giving Blake every chance to make the decision super-hard for us.”

“As a coach,” Gus Bradley said, “why do I want to apply anxiety? Why do I want to apply stress? I am trying to slow Blake’s world down, so he can learn everything he needs to learn to be a successful player. The plan is all about getting Blake ready to play. We’ll apply pressure, because you have to deal with pressure to succeed. But we’ll stay away from stress. We’ll stay away from anxiety.”

Blake Bortles was very impressive for the Jacksonville Jaguars and will begin taking first-team reps in practice this week.

Chad Henne will still start in Week 1, but Gus Bradley could go to Bortles sooner than expected.

Bradley feels strongly about Henne's play this summer and believes the veteran's "body of work" is more impressive than Bortles' performance to date.

"We're seeing progress being made," Bradley said.
