From what I've been reading so far, he has four options: Chicago Bulls, Los Angeles Clippers, Miami Heat and Washington Wizards and the commentators on the TV I watched were saying that he could even go to the Chicago Bulls because there he'll find a coaching staff made up of people he knows very well, like Billy Donova and others so it will be much easier for him to adapt, at least I think it would be a good option for him right now
than going to a team and having difficulties adapting and getting involved in some unnecessary noise, in short, as money talks louder, he can choose to go where they pay more money and have conditions to be at the top
Out of these choices, Clippers are the best team he can get. The Clippers sit 4th in the west right now. It is his best chance to compete for a title. He will be a good veteran guide for the young guards of the team. I also read that he will talk with the superstars of this team, Kawhi, and Pual George. I think if Kawhi likes WB to be in the team, WB will be in. I think the last word will be coming from Kawhi.
Lebron thought he would be awesome for the Lakers, but look how that turned out. Westbrook, wherever he ends up, needs to pick a place with unselfish teammates. The Lakers is just a joke that Lebron runs. Westbrook couldn't play with that kind of environment.
Plus, Westbrook skill sets do not fit how the lakers are run. His style collides with how Lebron plays.
They already have 2 players that are amazing at being 2 way players. Both PG and Kawhi are two way players, great at scoring and amazing at defence, they are definitely elite levels at that. However, they are lacking a decent point guard who can setup the game, because right now they end up with players creating their own shots, if Westbrook could become a bit more facilitator instead of a scorer, he could help these guys score a lot more efficiently and that could give Clippers a bit better advantage. Of course, it will all come down to if they can stay healthy because let's face it, Kawhi and PG get injured way too often, which is their real trouble.
I think the Clippers are doing good load managing Kawhi. He is on load management but they are still 4th in the West. That says a lot on how good the clippers will be when they go full force in the playoffs. Adding Westbrook will do them good as you explained. They will not have to create their own shots anymore if WB will be there to facilitate.
