As far as contributing in one's prime, one can make a huge case for others, who're not a part of the media circus of Bird, Magic, and Jordan.
Walt Frazier, the Big O, Baylor, Moses, and Hakeem were all tremendous in their respective primes but unfortunately, like Bird, they waited too long to retire which is why their latter years don't look so great in retrospect. The lesser, sort of one trick ponies, see Stockton and Malone "pick 'n roll", never garnered the same sort of all star admiration.
All and all, the difference between LB, Magic, MJ and the other all stars were the teams which they were on and the fact that those teams were not a part of either a historic or modern dynasty.
