KC wants Moss because they suck, and need cost-controlled youngsters with any MLB talent and because relievers aren't worth much. Despite the spastic nature of the trade deadline, the fact is quality relievers haven't gotten much. Marte wasn't why the Yankees put in Tabata, and Tabata's a loser anyway. Rauch got Bonifacio.
So those are my main reasons. I do not want a 37-year-old reliever for a prospect that is clearly impressive. (I find it striking that none of the posts above, in offering valuations of Moss, bother to look at why KC would ask for him.)
I think, too, that any deal needs to be looked at in the context of the Manny deal and any other deal, not as an isolated proposition. It seems obvious that the FO is working a "contend now but be prudent for the future" angle at the deadline, which I think is more evidence of the brainpower on Yawkey Way. If Manny leaves, this will be a new era. You build and re-mold and re-tool for that new era, not for 2008. Mahay is a 2008 answer only. Moss may not have a future in Boston, or he may, but he has more value than what KC is offering.
Much of this is wrong. First off, Moss is not an especially impressive prospect. SoxProspects ranks him 9th, and he doesn't even make Baseball America's top 10. He's 13th on John Sickels's list as a C+ prospect. He's got so-so power, so-so discpline, so-so average and so-so defense. That doesn't make him a bad player
, but who can he take a job from? He's not better than Drew, he's not better than Youkilis. He can't play center field, and if he's in left right now then the outfield offense would be too weak to sustain the team. He fits KC because they need average, but if he's any more than a bench player for the Sox the team isn't winning anything.
And Mahay is signed through 2009, so he's not a rental.
