I hate Chestbrook as much as the next guy but first off, Kawhi already clanked it off the rim on the previous attempt. Second, there was not enough time to pass the ball to Kawhi to get off a quality shot. He was open yes but time was very much against them he may have not gotten it off. Musclebrook got off a better look in this instance. So no, why so dramatic Kawhi it is what it is. You should have made it in the first place.

Edit: Upon further review, forget everything I said. Brook had a solid three seconds to execute a pass to Kawhi. He was already looking at Kawhi when he secured the rebound. The defenders probably close out on Kawhi as soon as he gets the ball but you still rather have Kawhi take the shot instead of Brook. Enjoy Westbrook fam more of this to come.
