I concur on the lack of power. For some reason, despite the presence of several pretty big names, I just feel like you're missing something in the power department. I might look to see what other catchers are available; Benito is an OLD MAN..... Juan Gone and Moises are both injury risks; get used to shuffling them between you OF, bench and DL.
I like you rotation. Very strong top to bottom. I'd like to see one more solid reliever. Izzy's good (although a bit of an injury question mark) and Baez SHOULD be decent, but....... MacDougal is not absolutely certain to retain the closer role, plus his 2nd half last year was, in a word, putrid! Gordon pretty much has no chance of closing this year. He's probably about fourth down the Yankee's list of possible closers, if Rivera goes down.
Overall, pretty good-looking team....
