Dan Gilbert
According to Forbes, Gilbert is one of the 25 richest people on the planet. However, this means there’s no excuse for the way that he treated LeBron James. He had the best player in the world on his roster but refused to support him. This was a terrible mistake because James lost patience with the franchise.

He loves Cleveland and his native Akron more than anywhere else. But he also wanted to win rings and that’s why he made the infamous decision to join Miami. Then Gilbert launched a venomous rant about the player. This was ridiculous because he created the circumstances that forced James to leave (via ESPN).
