By and large, individual players don't matter - it's total roster value. The key to moving a guy like ERod is that you do it at the point where you can get more wins back for him they he is worth to you - so you get better. THAT was Avila's single biggest failure. There was reasonable rational for moving most the players he moved, but he failed to get back the value that should have been there and that was the justification for those trades to begin with. The better example was when DD moved Curtis Granderson, he got back Austin Jackson and Max Scherzer. Max is going the HOF and AJ was potentially a perrenial 5 WAR player before the leg injuries accumulated. The idea of moving guys to teams reaching for the brass ring is that they are enough in WinNow mode to give up more absolute future value because the present value you offer is multiplied for them. But sure, if you are the seller in that situation and do not get more back then you gave up, then you have Avila's Tiger legacy.
