Football Outsiders is considered an industry leader in using statistical data to analyze NFL teams, and has been for years. They're using their data from the 2013 season to determine the biggest positional need for each team. For the Buffalo Bills, a team with several prominent holes, they have chosen offensive tackle as the team's biggest need area.
Here's the most interesting excerpt from the article (and of course we recommend that you read the whole thing), courtesy of author Scott Kacsmar: "Buffalo had such little success when rushing outside last season that a league-high 71 percent of runs came up the middle or guard." Perhaps the Bills had motivation for continually running C.J. Spiller up the gut.
Erik Pears is singled out as the player that the Bills should try to improve upon, which isn't surprising; what may surprise some are the cool words used to describe the play of left tackle Cordy Glenn.
Does this argument hold water for you, Bills fans, or are you of the opinion that another position is the team's greatest weakness heading into the offseason?
