While those are pretty lopsided, I would venture to guess that almost every team in the NFL accumulates a disproportionate number of their aggregate numbers against a smaller number of teams. In fact, I'm pretty sure that argument has been used many times on this board to defend the same points against the Patriots. "Yes, player X got 5 of his 10 sacks against the Bills, but every pass rusher has numbers like that!"
What matters more than the cumulative numbers is the potential the team has, and I believe Jacksonville has the potential to be a disruptive front. I'm not afraid of any team at this point in the year, because these are the rounds to embrace great competition and overcome them, but I'm not going to take anything away from the Jaguars defense. They're explosive, the Pats are going to have their hands full, and it's going to be fun.
