I love how many Spurs fans salivate at the mouth for a great defensive bigman to put next to Duncan that can knockdown a mid-range jumper on a consistent basis, but wouldn't consider KG who is arguably the best possible option. Hate or love his personality, the guy brings it every night and changed the Celtics into a perennial contender the last 5 years (at least when he was healthy).
I don't think it has a chance of happening (especially given Duncan's feelings toward him, KG's feelings toward Holt, lack of money to offer, the fact he said hes getting tired of moving, ect) but if he was willing you take him in heartbeat. I guarantee you KG doesn't get his ass chewed out in a closeout game after 1 minute and 1 missed assignment, then rides the bench for the rest of the game
