Even though I loved every glorious second of that punch he hit Koscheck after the bell, it was still a very unprofessional thing to do.. even if Koscheck deserved it.
Dana White was visibly pissed off at it because he is one of the key figures that helped bring MMA into the light & trying to shoot down any preconceptions that the sport is/was human cockfighting & that it is a respectful, safe professional sport.
That being said, hes said things in the past & upon time passing he has reconsidered his position on said matters. I'm sure if Paul Daley continues knocking people out left, right & centre & becomes even more of a profitable exciting fighter he'll soon change his mind.
Just look at Tito, hasn't won in years but still sells seats, mostly from people who want to see him get his ass beat but still..
