Actually, they want a SG, or an all star caliber player in return for tmac...Now, your initial thought is that no one would be dumb enough to send back that type of player for T-mac, but come the trade deadline, teams who start to panic, (see Chicago Bulls) or other teams who are out of the race want his contract. Right now, his contract has more value than he does himself, but if he plays well, then that can only attract better offers, not hurt them. If they take an expiring back, it would be for a good player with whom they can sign to a long term extension, like Bosh, even though Morey implied Bosh is not the player he is looking for.
