Here's my brief summary of many of the comments on this thread:
Various Talksoxers: We should shoot for A-Rod or Bonds or both.
TW101: Yuck.
Various Talksoxers: Well, TW101, would we or would we not be better with those guys?
Let me throw in my $.02 on TW101's side. Call me naive or whatever you want, but I'm not solely interested in rooting for a winning team. In other words, "Would we or would we not be better with A-Rod/Bonds?" is not the only question I ask as a Red Sox fan, and maybe not even the most important question. I mean, one of the reasons I don't like the Yankees (aside from the fact that I'm legally obligated to dislike them as a Red Sox fan) is that they're a bunch of personality-challenged corporate suits. Look at what happened to Damon when he went there. No hair, no beard, and most importantly no fun.
A (big) part of the joy of rooting for the Red Sox over the last few years has been the personalities on the team. I hardly need to give you guys any examples. My current favorite is Pedroia, a guy who is very easy to root for thanks to his permanent underdog status and tell-it-like-it-is approach to the media (the outstanding play on the field doesn't hurt either).
Now I'm not saying that adding A-Rod and Bonds automatically turns the Red Sox into a bunch of jerks. None of us knows what would happen. But I am saying that as a fan I'm not solely interested in winning. I understand that for the front office, it's a business and so they have to construct teams that will win. Fine. But if as fans all we want is a winning team, we'd have all been buying Yankees hats in the lates 90's.
Don't get me wrong: I like winning. But it's not the only factor.
To conclude with a ridiculous hypothetical situation: let's say the Sox get Bonds, Milton Bradley, A.J. Pierzsinksisnkinkski, and every other known jerk in MLB. Then they win the 2008 World Series. I'm not going to be celebrating; I'll be saying, "Look, a bunch of tools wearing Red Sox uniforms just won the World Series."
