Pro Football Weekly's team-by-team video preview series examines the Buffalo Bills today. PFW publisher Hub Arkush and associate editor Kevin Fishbain break down the pros and cons of the Bills' chances to make the playoffs for the first time since the 1999 season.
Reasons for optimism: Improved pass rush with new defensive ends Mario Williams and Mark Anderson; an offensive system that has proven it can move the chains; the backfield tandem of Fred Jackson and C.J. Spiller; new defenive coordinator Dave Wannstedt's influence.
Causes for concern: Skepticism that quarterback Ryan Fitzpatrick can be consistent enough; rookies Cordy Glenn and Stephon Gilmore starting at critical positions; the need for another receiver to emerge other than Stevie Johnson.
