tmac with the better individual talent, dirk with the better team talent. so i'll take tmac for the and-1 league and dirk for NBA or worlds. it's a no-brainer.
besides, if i was a GM i couldn't afford to have players like tmac, marcus camby, kmart or artest anyway. you'd never know when they'd be available and when they weren't. you can't build good chemistry if your star is constantly in and out of teh lineup...
