15. Paul Daley
Daley possessed one of the most lethal left hands in all of MMA. The English fighter is one of Bellator’s most recognizable fighters but broke onto the U.S scene with the UFC. ‘Semtex’ is a knockout artist and has devastating power. But he fell foul of the UFC after one unfortunate incident in 2010. He lost a decision to Josh Koscheck and wasn’t happy about it.

Daley threw a cheap shot at Koscheck after the bell and instantly attracted the ire of the UFC top brass. As tantrums go, this one proved costly because the promotion cut him. President Dana White promised that Daley would never fight for the organization again. While Daley was wrong to punch Koscheck, it was still a disappointing turn of events.
