A few points. I'm pretty sure tradition notions are that pitching and defense wins, contrary to what you argue. You also argue that defense is the true gauge of a players value. This is completely close minded. Obviously its both. Defense is not going to be what wins the east, offense isn't, pitching isn't, its gonna be the team that puts the combination of the three together the best, and I really hate when people argue that one doesn't matter, or is less significant, no matter which one it is.
No one said errors are a good judge of defensive ability, so I'm not sure why you felt the need to argue they aren't. Thats obviously true.
The press determined Coco Crisp is our top priority based on information from the front office. The fact that both Gammons and Edes have reported it makes it more likely. Sure its possible its not true, but given the reporters I'd say chances are they are right.
Also, I haven't seen anyone on this message board say we should give up marte for Crisp. I will say I would be happy if we get him for Mota and someone else, like arroyo/clement/Wells, or a 3 way where one of those guys goes somewhere else. The reports are that the Mariners are asking for Lester or Pappelbon in a trade for Reed. Judging by your stance on prospects I doubt you want to give up one of them, even though you say Reed is your top choice because Crisp would cost Marte.
