He's ranked #4 at lightweight he would not be jumping over many fighters. I think El Cucuy is the only one ahead of Nate atm given his monster win over Conor in the first fight. To refresh your memory a bit here Conor was supposed to fight RDA for the 155 title then RDA pulled out and Nate was a last minute replacement. Took the fight on 11 days notice which is why they fought at a higher weight. Nate asked for 5 pounds initially and Conor offered 170 just for the books. The only reason their rematch is not at 155 because Conor demanded the exact same stipulations as the first fight so there's no excuses. CM Punk won't be a huge draw unless he proves that he is a real fighter which at this point is hard to believe. I will say if he wins impressively he has a chance at moving needles.
