With Harden, an all star level player, joining the Clippers, they now have 3 stars on their roster.
IMO these teams also qualify as super teams just because they are built by stacking stars on their teams:
Clippers, Warriors, Suns, Celtics, Bucks, Lakers
The issue is health. Which 2 of Harden, PG, Kawhi and Westbrook are going to be out for all but the first 2 games of the playoffs?
