No it does not feel good. The Sox allocated $13. mil this year to a guy that had a poor chance of performing up to his contract and that is what happened. It was the wrong thing to do when they could have looked elsewhere to find scrub level pitching at a much more reasonable cost to supplant him in the rotation. Or they could have used the $13. mil toward chasing a better pitcher to fortify the week rotation.
The Sox decided that they were okay with the risk of Buch sucking. That is bad judgement and bad business. Now, partly because Buch has sucked, the Sox will need to spend extravagantly of your precious prospects or worse, front line MLB talent , to make the rotation sound.
The no brainer has been no bargain.
