As much as I like Buch, if he is still pitching like he is pitching and Doubront and Bard are still pitching the way they are pitching when dice comes back it might be Buch that gets a break to make room for dice.
My worry about Buch is that he is no longer the guy progressing up the Sox rotation totem pole and I really don't think he will be again.
He gained weight with a purpose for last season and now that is being looked upon as part of his back issues. So now his weight is back down again but he looks anemic at this point. So he needed the weight but his back would not allow him to pitch with it. Now the weight is off but doesn't that mean he is right back were he was before putting on the weight?
I think a 3 is as high as Buch is going to get and he might have problems holding onto that spot the way Doubront and Bard are coming on. With Cook in the immediate plans and dice not far off, this is a nice problem to have.
Lester had a great start last time out but I still think he is inconsistent and has still not even once succeeded when given the opportunity to be a stopper. So for now I still think the biggest issues in the rotation are at 1 and 3, not at 2, 4 or 5.
