a lot of that list is 20/20 hindsight and picking guys who are having unusually good years. melky cabrera was never a big-time prospect, was thoroughly mediocre the last three years and now is having a good year. same with francoeur - basically he was a zero win player for 3 years; now he's a 2 win player and it looks like the royals had some kind of amazing foresight. jj hardy was just undervalued due to his low batting average and contact issues, plus a poor 2009, not because he was some busted prospect. i agree that there are guys out there who are prospects that were cast off too quickly - maybin and sizemore strike me as two who fit that bill - but the problem is, how do you know who's going to be casey kotchman and who's going to be some AAAA guy who continues to fail every chance he gets? also, i take issue with the cameron maybin requiring "minimal compensation", as the padres did trade a pair of reasonably solid and young relief pitchers for him.
