Doing what the Denver Nuggets or Boston Celtics did, by raising one or multiple franchise superstars in their territory, is extremely tough. Still, by learning through failure, they were each able to win an NBA championship within the last five seasons.
The LA Clippers, on the other hand, are working with the two-time champion, Kawhi Leonard, as if the franchise drafted him. They have over-exerted their loyalty to Leonard, and it has produced playoff exits and season-ending injuries.
Granted, Leonard, when retired, will be regarded as arguably the second greatest Clipper in history, if a championship is not won.
