It's way too early to say. He came into a program that had trouble even winning a game, so no matter how good he is it's going to take a few years to turn the team into a good one. He's brought in a lot of recruits and recently got a commitment from a top 50 player, which may be a first in Pitt program history, but the real results are what happens on the field, so we will see.
Cool - hope he does well!
