I'll keep this short and sweet. If you're here you've probably already read all the reasons why this could be bad or good for Crow and the Royals -- service time, work with McClure, his bad season in 2010, etc. Bottom line for me is that if this signals the end of Crow as a starter, than it's not a good move at all. I'm not so much concerned about service time or whatever because pitchers get hurt, and getting six healthy years out of a pitcher is a good thing. It's a factor, but not a huge one, not one that will keep me from putting the best team on the field. I absolutely believe Crow is one of the best relievers the Royals have right now.
If Crow is eventually moved into a starting role, then this will all be forgotten. If not, I will be pretty disappointed that we don't get to see how he does.
