There's three teams that are clearly superior IMO:
1) Walt, MJ, Lebron, Duncan, and Hakeem- elite on both ends.
2) Magic, MJ, Pip, Duncan, Hakeem- you trade offense for size from the above, still an amazing squad though.
3) Magic, Jordan, Pip, KG, and Wilt would be an insane squad, too. Really long and absurdly athletic. Essentially position-less basketball with everyone being able to handle the ball and Magic and Pip being able to defend 1-4; and probably 1-5 in the case of KG and Wilt. They'd be a terror in the open court.
