Magic played on a team that was loaded and may have won finals with out him, Kareem team won a finals with out him... Russell and Chamberlain played in the WNBA while LeBron took expansion team talents to the finals and was always the best players on his team that won..
The assertion Lakers win championships without Magic doesn't merit a reply. Any team Kareem played on was an instant title contender. 6 of Russell's 11 championships were against Jerry West and Elgin Baylor of the Lakers. Hardly WNBA talent. As far as loaded teams go, Miami Heat were pretty loaded as well as the Cavalier's.
