These stats don't surprise me, both Tony and Tim are great in the clutch at actually making the shots. not just drawing fouls. Manu is one of the Top 10ish 4th quarter players in the league, but as a last possession player, I don't think he is as good as Tony or Tim. I've always thought the same about Kobe. Incredible 4th quarter player all the way down to the last shot which he usually bricks.
Side note: Manu is one of the clutchest rebounders I've ever seen out of a guard. Very underrated part of his game and when I'm watching a close game, I always expect Manu to come up with tough rebounds down the stretch, and he almost always does.
