He overpaid him because he is Lebron's friend. Its only 3 quarters into game 1 but the dude is a zero on offense and I don't see him dominating the boards the way he did in the finals against the small ball Warriors.
It is kind of weird how pro-Lebron media members will spin that as something good about Lebron. Granted if I was him I would do the same thing if I could get away with it, but generally in sports you get fucking destroyed in the media and with the fans if you do anything other than try hard and be clutch on the court.
Lebron could have fired his coach but chose not too. He's a good guy
