As its been presented, I would say that Cleveland would win this trade, however:
1) The only confirmation of such a deal is coming from someone's brother and the Boston Herald's Tony Massarotti, neither of whom I have much confidence in. The more reliable Boston Globe has yet to confirm the trade after 12+ hr. Assuming that it does happen, I would imagine that there are some (possibly mitigating) details that have been left unreported.
2) Some of these details probably involve an exchange of prospects, and (given the age and projected performance/career for Marte) probably more quality headed in the Boston direction than the other. Ryan Garko certainly makes a lot of sense, and one doesn't have to assume that Shapiro is incompetent to consider his inclusion. Garko is an interesting offensive prospect, though he'll be 25 and he's apparently not much of a catcher and would likely have had to switch positions even if he wasn't blocked by Martinez.
3) Even though, from what I know, I would prefer the promise of Marte to that of Crisp, perhaps Crisp has been somewhat short-changed. This is a copy of a post by Eric Van at sonsofsamhorn.com, where he considers the projections for Crisp made by James and Shandler:
Bill James: .296 / .348 / .442
Ron Shandler: .290 / .339 / .468
However, he'd be moving from the second worst hitter's park in MLB, 2003-5 (tied with RFK and Dodger Stadium) to the fourth best. In particular, playing half your games at the Jake reduces HR for a RHB by 14%, while Fenway gives a 6.5% boost. James' projection of 13 HR becomes 16, Shandler's 20 becomes 25. James projects 34 2B, 4 3B, which becomes 38 2B, 5 3B.
BA gets a boost (from -2% to +1.5%). Let's see . . .
Crisp in Fenway, BJ, something like .307 / .358 / .479 (Damon: .292 / .361 / .425)
RS, something like .300 / .348 / .514 (Damon: .295 / .359 / .429)
In my mind, a lot hinges on how well Crisp can play CF. He's certainly a very good LF, but when he's played CF, the metrics show him to be somewhat spotty. We'll see. But the above would be excellent production from a CF.
4) Finally for those of you bemoaning the fact that the Red Sox should have just traded Mota for Michaels, what makes you believe that this was/is a possibility? The Phillies are apparently willing to trade him for a middle reliever that they believe is of comparable value, not just any old middle reliever that's thrown at them and not from any compulsion to help the Red Sox out. Betancourt and Riske are both superior options.
