The fellas at College Football News took the time to study the question, and came up with a ranking.
Pitt is on their list. But at #8, not #3. You ask who else could be better? Well, those fellas say:
Clemson, Wisconsin, LSU, Oklahoma State, and Baylor (in addition to Bama and UGa, as you noted).
Now, the list becomes a bit suspect when you consider that OK State just gave up
44 points and
546 yards to a MAC team. I don't care how bad the rest of the defense is, a top-10 defensive line should never allow that kind of production by the opponent.
So...these fellas could be wrong. Then again, Pitt is #8 on their list...so if they're wrong about some teams here, maybe they're wrong about others.
Anyway, Pitt's d-line is supposed to be good, yes. But not better than anyone in the country not named UGa or Bama. In fact, we personally will face off against three teams with better d-lines than the Panthers this year. If we're getting back to championship football, beating teams with good d-lines is a part of that path.
Go Vols!
