The Twins could easily be hurt by such a decision too. To use your example numbers, if May is good enough to be a $14 million starter, but we're using him to fill the spot of a $4 mil reliever, that's a lot of excess value we are leaving on the table. We'll have other starting options, but it's highly questionable whether there will be five better than May. And just keeping extra starters and starting prospects for depth, in the event that May is needed in the pen, will have a cost. From re-signing Pelfrey with money that could instead be used on a reliever like Neshek, or passing on a trade of Milone, or protecting untested arms like Duffey, Rogers, etc. And May's success in the pen may lead to us being even less aggressive on the FA relief market than we were in the July trade market, regardless of whether our team would be better with May starting and a FA reliever added to the pen. May being a bullpen weapon certainly has some upside. But I'm not sure I trust TR to properly use it as an option to improve the team overall, rather than as an excuse to avoid making certain improvements.
