Who has the most to gain/lose during the rest of the season?

I think it's THJ. If he can find a way to be effective in a reduced role the Mavs could keep him around next year. If not, this may be the offseason they dump him for a 2nd round pick (assuming they can't package him with a pick for an upgrade) and look for guys like Exum/Hardy/DJJ to take his minutes.

It probably should be Kidd, but it feels like the Mavs are committed to him. He's likely to stick around no matter what happens the rest of the season. Other guys like PJ and Green have a lot to prove but aren't likely to be dangled in trades.
