Rogan had Brendan Schaub on this week...of course they gave the rosiest endorsement of the fight, but they made some interesting points (also, some major Jon Bones Jones ass kissing went on, which became outdated in about 24 hours). They were way more convinced by the Mag sparring footage than any of us were, and remember that Schaub has a boxing background.
They pointed out that Mayweather has ****ed up hands after all these years. They are a genuine concern, especially in 8 oz gloves.
Schaub says McGregor will have about 5 tricks he can pull out of the bag and he needs to capitalize big time on at least one of them. He'll show Mayweather some things he's never seen before, Mayweather will "download the new fight data" and it won't work again for the rest of the fight. For example, Mayweather has never seen a punch thrown from a karate stance, which could be interesting.
