That would be a very interesting fight. Nog on a good night if he can stay on the outside avoiding the big shots from Roy, i think he can pick him apart and win. I don't see Roy being able to do anything with Nog on the ground, i doubt he would even try taking him down. I wouldn't be surprised if we saw Nog trying to go the ground at some point in the fight. He's actually the bigger stronger man of the two even though Roy weighs more, and i think he can control Roy on ground with his size and his grappling technique. But if Roy can connect with those big shots on his feet, i can definetly see him winning this one by KO or TKO. I would love to see this fight.
