The Bills traded for LeSean McCoy in the offseason and hired Rex Ryan as their head coach, while they'll go with either EJ Manuel or Matt Cassel at quarterback. That's all the evidence needed that this will be a run-first offense.

Key to the whole situation, of course, is whether the offensive line will be good enough. Buffalo is doing some mixing and matching, particularly at tackle, trying to come up with the right combination.

Cordy Glenn has been the team's left tackle, but they're trying him out on the right, as well. Seantrel Henderson has been the team's right tackle, but he was demoted behind Cyrus Kouandjio at a recent minicamp, probably in part for being late attending.

In our magazine ranking the league's offensive lines, the Bills graded out as the 14th-best line, so slightly above average. They'll be starting Richie Incognito and John Miller, most likely, at guard, with Eric Wood at center. No elite players in that group, perhaps, but nobody who you can say, this guy is a major liability.

Our concerns with the offense are less the line than the quarterbacking, which figures to be below average, and the fact that McCoy might not play full-time. Buffalo has a lot of other backs, including Fred Jackson (still!), Anthony Dixon and Bryce Brown, and it's possible all those guys will have a role.

However the Bills position their tackles, though, the line shouldn't be a problem for this team. Serviceable play at quarterback and McCoy making it hard for the team to take him off the field; that will be key to the offense's fantasy value.
