Sure we can. The key will be the depth behind them. Lets assume JJ is back next year, the rotation will be (in no particular order) Dickey, JJ, Morrow, Buehrle and Happ. Depth behind is Romero, Stroman, Nolin, Hutch, Drabek?
AA would likely need to bring in one more guy who is a #3 or better. Bump Happ to AAA and have him ready as the #6 right out of spring training. The other 5 guys below in the depth charts will get more time to work on things in the minors. I feel a lot more confident about the potential depth heading into next season, the bigger question will be how the guys in the rotation hold up and perform.
