What is the Best Pitching Role for Joba Chamberlain?

I would like Joba Chamberlain to be Starter for the Yankees, but I rather see Chamberlain to a Starter sometime next season than sometime this season. I want him to be in the Bullpen this year, because I'm afraid if he comes a starter this season it will effect the bullpen and the starting rotation. To be honest, I want Jonathan Albaladejo to be the starter for the Yankees this season if either [Phil]Hughes,[Ian]Kennedy or [Mike]Mussina Continues to struggle and not pitching constantly. The Problem with Joba being the Starting Rotation is that you have no one to be an eighth inning setup man to Mariano Rivera. There is a possibly that Chamberlain could pitch inconstantly as a starter. 

Having Joba in the bullpen this season is better than having Joba in the Rotation sometime this year. because what happens if he struggles in the rotation or he goes on the DL with an injury while pitching as a starter, that would huge mistake on the teams decision. If I were the Yankees, I would have Joba pitch in the rotation sometime next year,because it gives Joba an opportunity to pitch at least 30 games. If he doesn't do well as a starter, I'm hoping that Chamberlain will continue to be a 8th inning pitcher and eventually becomes the new closer for the Yankees after Rivera retires from baseball.
