Whether you consider Kyle Williams the team's (relative) "worst" starting defensive linemen or its best, he will be of critical importance to the Buffalo Bills' success in 2015.
Put simply, Kyle Williams has been one of the Buffalo Bills' best players for a decade now - despite the fact that he has routinely been overshadowed, to varying degrees, by higher-profile and more productive teammates.
People tend to forget that Williams walked into Buffalo's starting lineup as a fifth-round drafted rookie out of LSU in 2006, ahead of draft classmate John McCargo, a first-round pick.
