Kawhi’s legacy in NBA history is a very unique case. He has two championships and two Finals MVPs for two different teams, which would lead you to believe he’d climb most objective rankings pretty high. On the other hand, he’s only had three seasons (of 8, 7 if you don’t count the 2017-18 season) in which he put up allstar / all NBA seasons. I think the hesitancy to rank him higher is because of that, shortcomings in regular season production. When he’s playing and healthy, he’s been universally viewed as a top 3 player in the game. And he’s closed the deal twice in the playoffs, as THE guy. I think his career likely needs several more all NBA caliber regular seasons to cement his legacy as a top 25, and possibly at some point top 10 player.
Right now, if he were to retire today, I don’t have him down as a top 25 all time. So I think the ranking is probably high.
