There are many times when White didn’t practice what he preached. He infamously shredded the legendary Kimbo Slice when he fought for rival promotion, Elite XC. Slice built up a cult hero profile after many street fights before moving into professional combat sports (via Bleacher Report).
Then the UFC did a U-turn and signed Slice after his deal with Elite XC expired. Suddenly, White backtracked and hyped up the fighter like he was the greatest in history. Some people will argue that this was good promotion. But the initial way he verbally abused Slice was horrible and says a lot about his character.
