Silva is actually an old guy. I think he's 37 or 38. So he's not a spring chicken. Interesting fight, considering Roy is so shot and Silva has decent boxing skills and has actually been praised by Freddie Roach. But I doubt the UFC lets the fight happen. Dana White will guard Silva the same way Arum is hesitant in letting any of his cash cows fight Floyd or any elite from GBP.
silva boxing skills look good in the ufc because the guys he fights have abysmal head movement themselves, against a below average boxer he would get destroyed
