The booing was absolutely bang out of order and I felt horrible for the guy during that post fight interview.
Dos Santos survived five rounds against a relentless Cain Velasquez who gave him no space to breathe what so ever. Where every other single HW would have fallen and succumbed to strikes in the fight, JDS NEVER gave up, and was always trying his heart out.
That's a testament to his true warrior spirit and just proves how skilled of a fighter he really is. People have critiqued Cain for not finishing Dos Santos, but I don't think that's fair. Cain couldn't finish the fight because he was fighting Junior ******* Dos Santos, one of the most elite HW's to ever compete in the sport.
Great fight, terrible audience.
