The big question would be if the Lakers/Celts would be able to dominate with old school post up basketball or if the other team could use its superior shooting and quickness to overcome the disadvantage with the bigs.
Walton's number isn't retired by the Celts right?
Doubt it. But one last word on this. IMO if you put a player on an all-time list for a certain team, you should be getting the player he was for most, if not all, of his tenure only on that team. So putting Walton on the Celtics All-time team gets you the gimpy Walton who played 15 minutes a night averaging single-digit points, not the mid-70s Portland version of Walton.
