I'm still looking for those news if they'll take Irving and if there's a chance that they'll take a player from the Nets, it should be Irving and not Durant.
Davis and Westbrook both have a problem. Davis is injury prone, while Westbrook is inconsistent, so if they could solve that problem then maybe once again the Lakers will become a championship team. Right now, the top favorites in the past season are struggling, and they are not anymore the favorite to win now.
Most likely they will keep Davis, remember that there were news about two weeks ago that Davis will be the first option and they want Westbrook to be a corner 3 shooter. And then Lebron distributing the ball, so that will be their initial plan.
So I don't see Davis being in the trade block for Lakers, most likely it will be Westbrook first. But since there is no news already and it seems to die down, maybe there will be not trade, Westbrook staying in Lakers and then Irving with the Nets.
