Last year is last year. Both the Bills and Jags are different teams. The Jags were superbowl contenders before anybody even saw them play a game. This season, the Bills look to have taken a step forward, whereas the Jags seem to have regressed slightly. Jax failed to adequately address their glaring need for receiving talent(Jerry Porter is not a fix and he can't even stay healthy) and they lost the core of their offensive line to the injury bug.
I'm not saying the Bills will win in a blowout, it's common knowledge that the Jax D is tough. We may have some problems getting the offense into a solid rhythm. But, it is a commonly held perception that games are won and lost in the trenches, along the offensive and defensive line. In this battle we win hands down, even if Peters doesn't play.
I billieve Jax will have a tough time running the ball against our front four with the injuries they've sustained and have a lot of trouble protecting Garrard, which will be a big help to our DBs(who, in my opinion, already overmatch the Jaguars' receiving corps).
My call is a fairly tight one: BUF 24 -JAX 17
