Any NFL depth chart published on the last day of April is going to be unofficial, so the projected Buffalo Bills depth chart that you'll find after the jump is, obviously, extremely unofficial. We're not likely to get a good idea of player roles, units and rotations until training camp and the pre-season, so along with being unofficial, this depth chart is also highly speculative.
Buffalo has added 24 new players to its roster since the close of the 2009 season. That list includes nine drafted rookies, eight undrafted free agents (with more to come) and seven free agents, varying from the highly-touted unrestricted variety to players essentially signed off the street. I also assume many of you will take issue with some players' slots, so let's hear it in the comments section.
