The most crucial info to properly answer this is missing, what are the keeper round costs of your players and his? Not just the players you are proposing but also any super keeps you might have nabbed a little later ( Hosmer, Marcum etc...) I really don't see how that team is last place, but he would have little reason to trade either Braun or Cano without landing great keeps. If he is indeed rebuilding? If he shopped them (which we'd recommend he do if he posted here) he'd surely get someones best keepers. Also I'd focus on one stud or the other. If he has any sense at all he'd realize he'd get more value selling them in separate trades to different owners. I'm not saying don't go for both, just that I'd expect him to prefer to not lose both chips in one trade.

Cmon Bud NOW is the time to sack up and force feed an Olympic style drug testing program down Fehr's fat throat and save OUR game from these blatant cheaters!
