I'd be surprised if Abel KOs Pearson. Pearson's defense is pretty damn high level, and Abel is not a combination puncher. He wings bombs. Against a disciplined boxer, thats not a good look.
Abel should be bigger, and of course that helps if he looks for a wrestling heavy gameplan, but honestly I love Ross in this spot. I think hes a bad matchup for Trujillo big time if he avoids prolonged periods of being on his back. He will probably be one of my bigger bets, especially if that decision prop is juicy.
