I'm starting a dynasty with the Warriors today, and will be putting next years rookie class into my draft. Cliffard Robinson is easy to trade, because its likely he will retire at the end of the year anyway. I wont be doing many trades, too try and keep my dynasty as realistic as possible.
I would try to trade speedy to get a quality big man back. You may be able to get someone half decent back from the Lakers or houston as they are Point Guard deprived.
