I think the Wizards have cap room because they have young players and only Johnathan Wall has a high salary.
LeBron could make the Wizards a very good team and as a well spoken black man, he would do very well there.
The best fit for LeBron would be Houston or San Antonio.
LeBron has never liked one on one isolation basketball. If you look at his HS games, he loves the free wheeling ball movement that the Spurs and Rockets play. He would rather be Magic Johnson than Michael Jordan. He likes to make the great pass.
I think Lebron is smart enough to play for a team where there is no state income tax! He did that when he jumped to Miami instead of NY. No way he plays in California except road games. 13.5% income tax on millionaires!
