Ooohh.. I'm likely going to have a lot of people disagree with me on this one, but I'd leave Sherrill alone - Having just switched over to the Orioles, I have a horrible feeling that he won't post the numbers he did with Seattle; while dropping Meche for him likely wont make or break your season, Id still wait and see on him...
hopefully no one else will notice either, and youll get a few spring starts to see how he's handling the new environment/team. As far as your team, the offense is balenced, and looks like it will do well for you, but your pitching, is tight, as you said. I don't think your in TOO much trouble, but maybe try to work out a trade (maybe even with Sherrill -- hah! how great would that be

), packaging someone like abreu with meche and get a mid tier - upper tier pitcher. Idk, I've never been good on valueing out trades. Either way - Good draft overall, and good luck this season!
