Bills coach Gregg Williams doesn’t fear going into the last year of his contract. Why? His defense is so much better than last year, and Drew Bledsoe enters his second season as the Bills quarterback. The key of training camp is making sure no injuries happen to the front seven of the defense. With Sam Adams and Pat Williams at defensive tackle, no one will run on the Bills. Linebackers London Fletcher, Takeo Spikes and Jeff Posey will be chasing down players all over the field. The defensive players have bought into Williams’ scheme. A big season could earn Williams a big contract.
