Maybe that Kawhi has 51/47/88 shooting splits, while Melo is down at 42/35/84. Not to mention Melo committing 3 turnovers/game to Kawhi's 1 turnover/game.
Maybe that Kawhi also adds 2 steals and 1 block to those numbers, while Melo has half that.
Maybe that Kawhi's PER is 4th in the NBA at 27.5, while Melo is back in 40th place at 20.3
Maybe that Kawhi is one of the best defenders in the game, while Melo is average at best.
Maybe that Spurs have one of the best records in the league and are Finals contenders, while the Knicks have a losing record and aren't in playoff position.
Maybe that Kawhi just keeps looking like an MVP candidate against every other MVP candidate he faces.
