One thing that turned him off in Miami is he did not have confidence Arison would, so there's that. Guy spent more in tax over a 3 year period than every team COMBINED.
Didn't Miami let Brogdon go partly because they didn't want to pay him and Middleton?
Don't know and don't care about Miami's situation. I just know that Dan Gilbert didn't do anything different than other owners serious about winning a title. Also, D-Wade starting to breakdown physically was part of the reason he left too.
And Lebron signed deals designed to hold Gilbert's feet to the fire the entire time he was there to make sure that Gilbert spent whatever was necessary. So there's that.
