The injury concern is overblown given he has not missed a game to injury the past two years, and that he has missed a total of 14 games in 11 seasons of his career. However, at his age, it is certainly possible, but that is what the depth is for. When healthy, other than Diggs and Beasley, the Bills have no other WR in the same class as Sanders. Not even close at this point, while they do have some potential. Sanders is far better than Brown was and the Bills needed that upgrade. If he does go down, I feel confident that a combination of Davis, Kumerow, and Hodgins can fill the void, but make no mistake, Sanders is more dynamic than any of those options.
