Ok so I'm going to tweak it just a bit and say it's a 12 man squad and each has to play their natural position so, for example, Dave Cowens can't be listed as a PF. With that in mind, here goes:
Centers: Russ, Kareem, Wilt
Forwards:Bird, Duncan, K Malone, Havlicek, Baylor
Guards:Magic, Jordan, Oscar, West
