I think this thread is getting too personal, but to throw my two cents in, we're talking "prospects" here, and the definition of a prospect is something expected but hasn't yet occurred. Let's throw track records out the door here. Everyone is a minor leaguer and some of those being touted as being better than Longoria are a couple years younger than him, if I'm not mistaken. Who's #2 vs. #3 really seems to be a silly question compared to some more pertinent questions one might be asking. Everything is subjective. And depending on your mode of measurement, a case can be made for Longoria or someone else. Hell, I'll make a case that my unborn son is a prospect worthy of being ranked in the top 100.
Also, I have Longoria on my team, and I could drop him and pick up Maybin, but I'm not going to, simply because everything I read, has Maybin merely a maybe (how's that alliteration?) for 2008, and in terms of fantasy baseball, that's a hell of a long way off. I could point out to you several can't miss prospects that never made it because of injuries, drugs, etc. Longoria seems closer to the major leagues for several reasons and for that reason alone, I'd rather have him on my squad. But if you say Maybin is better, I'm definitely not going to argue with you. Just tell me whether you'd drop Longoria, Kemp, or Tulowitzki for him and why.
