haha not 15 but at least 5, especially if it was during Lakers (with Shaq Kobe) Spurs (Duncan), no more than 3 to 5.
Jermaine O'Neal in his prime wouldn't last with the rest of that group. Pierce might have his struggles with the team play as well, but that's based on how he played the crap he was stuck with in his prime.
O'Neal was too much of a me first guy to fit with what you're implying this group would be. Perkins would mean a lot more to that group than O'Neal.
I'm not joking. It only worked because all those guy were post-prime. prime players have prime attitudes. All those number one guys, it wouldn't work. Even Rondo, he doesn't care about scoring, but he still wants the ball in his hands.
