I'm going to go ahead and say it is what it is. Pearl has a history of very good success everywhere he's been. He hasn't forgotten how to coach or what got him all those wins at different places. I remember his teams at Tennessee, but I honestly couldn't tell you what style they played or if there was some particular offense they ran. The one thing I do remember is them being very big and athletic. I think he had some 6'9" guy named Chism or some shit that always seemed to wreak havoc in the middle.
Ultimately, I think Pearl's success is going to come from simply out-athleting (If that's a word) most other teams. Even with no real go to offense, we still can score in bunches at times. It may just be that he needs a couple more recruiting classes to load the wagon up and say, "I'll put mine against yours and we'll see who scores more."
