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
I think this team could work. Russ and Harden are both great regular season players, while Kawhi and PG are great playoff players. Rely on the first 2 to get to the playoffs, and then unleash Kawhi/PG when it matters.
