None of the superstars from the past got together like little school girls and picked their favorite team to play with each other at. They were loyal to and stuck it out with the franchises that drafted them and waited for the franchise to be built around them. MJ, Magic, Larry Bird, Olajuwan and Drexler, Kobe, Isiah Thomas, etc all stuck it out with their original franchises and won championships.
Drexler 12 years vs. LeBron 6 years. HUGE difference. Kobe wasn't at his original team long enough to get unpacked.
