First of all, Katoa is a very good RB. He could easily be getting more carries at a number of P5 schools if not for Allegeier. We dont really have any clue how good the rest of the depth chart is because there is simply no reason to give any of them the ball. When you have 2 backs easily capable of handling the load, the third guy just wont get any touches. I suspect Davis and Ropati will provide plenty of production. With virtually no one graduating this year, they will have a more experienced O line to run behind and the same stock of elite receivers able to stretch defenses. I am not saying they will replace Allegeier by any stretch but they will do enough.
