Westbrook was actually +5 in the game last night, the Lakers were -12 in the 13.5 minutes he was on the bench. But that pretty much illustrates the fundamental problem with the Lakers roster i.e. it is just a steaming pile of garbage. If they had Davis, James, and Westbrook all healthy at the same time (even with Russ' poor fit), it would mask a lot of the other issues the team has, they've just had so few games this year where all 3 of those guys were healthy. Davis missing time has to be expected, same with Lebron. That is in fact why they made the trade for Westbrook i.e. they wanted a ball dominant lead scorer for the games Lebron was going to be out, they just didn't do a good job at all surrounding them with quality enough players. Just re-signing Caruso, Matthews, Shroder, and Drummond would have significantly increased the talent on the team, but they just didn't do it because they didn't want to pay that much luxury tax. The end result is a terrible team.
