You can't be considered great unless you win WITHOUT a supporting cast?

Look at LeBron in Cleveland, Garnett in Minnesota, Kobe between Shaw and Pau, Jordan in the 80s, Oscar Robertson, Wilt Chamberlain and many more examples. Great players haved carried teams a lot of regular season wins and the playoffs. But no matter how great they were, they couldn't win championship until they joined forces with another great player or two. Basketball lets individual talents show, but it's still a team game. If you can't be considered great until you win it all with a weak supporting cast, then no one can be considered great.
