Here's my all-time LA Laker team:
Center/Power forwards
Kareem Abdul-Jabbar
Shaquille O'Neal
Wilt Chamberlain (back-up)
Small forwards
Elgin Baylor
James Worthy (back-up)
Guards
Ervin "Magic" Johnson
Jerry West
Kobe Bryant (back-up)
Only eight players, you say? That's all that would be needed. And the team would never lose a game. Also, these are the only truly great, Hall-of-Fame-type players the LA Lakers have had.

I don't think Kareem and Shaq rebound enough to be power forwards, and I don't think they could defend as well as Wilt, either. As I said earlier, Wilt was still rebounding with the Lakers. But I like your idea of rotating the three, and Elgin for Worthy is not a bad tradeoff.
You have a pretty good team, but even in his prime, Jerry West was injury prone. You need a backup for him when he breaks his nose.
