At this point, I think everyone wants the team to lose.
Showcase the players you want to move
Right; that's why I prefer starting TT over Ariza. I'm not sure Sweetney is ready to be "showcased." I don't mind continuing to give him 20 to 25 mpg.
I'd definitely cut Marbury to 30 mpg, play Jamal at point, and give Butler a little PT (but not enough for other teams to get interested in him!)
