The final turnover being the most costly? They are never in that position if Graham does not muff a punt at the 6 and then fumble the ensuing kickoff after the TD. Pitt might have been bigger, but they were not faster.
lionfan - Was at the game 2 years ago and the refs had zero to do with Commerece getting beat. And to answer your other question. The Refree probably said the ball was tipped at the LOS and in that case there cannot be pass interference.
