Kelly made his own problems in Philly — trading away extremely talented players, replacing them with players who didn’t fit what he was trying to do, being completely predictable on offense (stretch run, anyone?), ignoring the importance of having a good defense and being stubborn about running a play every 22 seconds (he’s seemed to have gotten over that last one). His system worked when he had players. But doesn’t everyone’s? He’ll be back in the Pac 12 in 2 years.
