Fantasy trade advice, fair?

Getting Sheffield while he's at low value is a great grab, and he'll be getting back to his usual form soon, and ditching Rivera for Nathan is another good call too. My only problem looking at this trade is there's too many players involved, at this point in the season if i got that trade, my roster would almost be set. Nobody wants to tweak with the roster they want once it's already in place. your best bet with that many big names is to cut it down to the players you want most, and he'll be more likely to go for the trade.
