This is a fair deal, but I wouldn't classify it as a no-brainer. My big question is, who is Butler replacing at DH for you? Can you get a SP besides BuchHolz coming back? A prospect other than Kelley? Butler is good and Buchholz certainly holds value in a 30 team league, but overall Buchholz and Kelley are very bleh.
That said I would shop Romero as he was a bit lucky last year - he's definitely more of a mid 3's ERA guy. That's not an insult for a pitcher in the AL East and I even think he has a little more K potential, but I'm convinced he experiences some slight regression in 2012.
I would hold out for more solid secondary pieces simply because theoretically DH should be the easiest position to find WW help next year. If Butler fills a hole at 1B instead I would jump on it.
