Look, the Lakers could tie the game and bring it to OT, but it's Westbrook who took the last shot in the 3 point line which I think is not a good idea as Westbrook's 3 points percentage is awful. I don't know if it's designed for him, or maybe he just took the liberty to shoot trying to be a hero but failed.
We can not assume his true intentions, but regardless of what happened and without Lebron James, I think the Lakers did what they think was right, Russell is pulling up 3 points shot in the first half and they are leading the game so much that their defense just withers in close to the 3rd quarter, I really thought they can pull a win here, and Lebron James is already celebrating from the bench, I really think that the Lakers can surely win that but I think the lead gave them confidence that the Thunders would not make a comeback, but maybe giving the ball to anyone that can really make that desperate shot, I think Russell Westbrook is not that guy,
And yes Lebron James could be gone for 1 week, and right now Anthony Davis has a thumb injury but maybe he can still play it next game.
On the big 3, I think only Davis is clutch, even Lebron is not consistent, but in that particular game, I think it should be Melo who should take the last shot as he is more accurate than Westbrook and I've seen lots of games where he finish with a win when he was still with the NYK.
