Which is why I said IF but reports are saying that all indications are that Bosh will play next year. You're right about the Dragic thing though, that was my fault. Even then, Richardson at the 1 would be fine because he wouldn't need to handle the ball as much with Wade and KD. The bench would be weak outside of Winslow and TJ if they match whatever offer he gets though.
Basically only way it could happen is if they can trade Dragic and McRoberts and a couple guys take less than max. Whiteside has already said that he would take less if it meant KD coming and although it's not likely bc of how things have gone Wade might too
