San Antonio is 27-14 this season. Leonard has played in 8 of those games and the Spurs are 4-4 in those games, making them 23-10 without Leonard. They even won all 4 games that Leonard didn't play since Leonard came back. I think there may be some credence to the fact that Leonard has become overrated. He is a scorer and a great defender, but he isn't a guy that can run an offense or a team. His passing skills are poor (for a top level player). He isn't a good rebounder. He doesn't have great size, speed, or athleticism. He uses his intelligence and instincts incredibly well, but he isn't some physical specimen. He is a great player, but I think this season has shown he isn't in the same class as Lebron or Durant (or Giannis).
Kawhi is one of the most overrated player in the league, he got covered so much by Pop's systemCouldn't disagree more. The Spurs win a lot of games but I can't think of guys who look a lot better in Pop's system than elsewhere. Simmons, for example, continues to blossom since leaving the Spurs. I have Kawhi in the Durant and Lebron tier.
Moranis with time I honestly became a fan of your pragmatic perspective, but I disagree with your take on Kawhi. You say he doesn't have a great size (It is enough not to get pushed towards the basket by LeBron, a true and definite test of that), speed (OK, not elite as prime DRose or IT, but still excellent for his size IMO), and Athleticism (includes, but is not limited to aforementioned speed and size. He is explosive, has 2 sizes bigger arms and hands than his body would suggest, while retaining the agility and dexterity. Personally, I think that pound for pound there is no stronger player in the league.
Sure the regular season record numbers would back up your opinion, but when Kawhi is 100% healthy he makes fans worldwide believe that the epic Warriors can be beaten.
