The Bills hope to have a battle between veteran Geoff Hangartner and up-and-comer Eric Wood for the starting center position before the new season. When Hangartner went down with a sprained knee late last season, two-year veteran Eric Wood shifted over from his right-guard spot to start the final four games at center. "We think Eric Wood was the best center in the draft coming out," Bills general manager Buddy Nix said earlier this year. "Obviously he wasn't (fully) healthy. But when he gets healthy, there's a good chance that's where he'll be. We'll just see. We'll play the best ones." The Bills are enamored with the physicality of Wood, who fought his way back in 2010 from a severe leg fracture. They also treasure Hangartner's intelligent play -- he scored 47 out of 50 on the Wonderlic before the 2005 NFL Draft.
