With the MLB Non-Waiver Trade Deadline fast approaching (Monday, July 31st at 4:00 pm Eastern time), there are numerous rumors and predictions being tossed around. Baseball fans love rumors; they provide something to talk about. I, however, prefer to re-evaluate trades that have happened in the recent past, using hindsight to provide clarity on how well each team truly made out in the deal. Since prospects are such a major part of trades in the MLB, it often takes a few years to really determine if a trade was worthwhile. Therefore, I have gone back to the 2012 and 2013 trade deadlines and have handpicked three deals that I believe are worth revisiting.
