Gasol's on the West so he can't be in that Eastern lineup. I seem to remember in last year's All-Star game, the West at one point put a lineup of 4 centers and 1 point guard in the game. I can't remember which players specifically, but I think it was Nash, Shaq, Yao, Duncan and Webber maybe was the last one. Dirk Nowitzki said that he wanted to replace Nash in that and run the point for that lineup. Now THAT would be awesome to see.
This year, they could do Yao at center, Shaq and PF, Duncan at SF, Dirk and Brad Miller could share the guard positions.
