If Breland didn't allow Ayala to maul him, I could see him outclass and outbox Tony for the UD.Mark's height would cause Tony some serious problems.
Mark Breland would be like Mario Maldonado - Both hurting and flooring Tony Ayala Jr. early. But Mark would gas out by the 5th, and the body punches would take their toll in Round 6, where mark is TKO'd.
