Lakers won against Thunder after a very close fight by just margin of 2 points so it's great pick to pick +5.5, but Lakers played wonderful today and beat Thunder that is great comeback and will boost their morale after back to back lost and now Thunder lost 2nd in a row there.
They deserve the win, that's what happens when Thunder was heavily favored. Westbrook can't do it himself, and it was already predicted by the lakers that westbrook will be going to make the last shoot. Lakers played like a team, and they have complete balance scoring, that's why they win.
