Before the fight I was already skeptical. Had this idea he was running through LHW's because of physical advantages, and low and behold, when he runs into someone of similar proportions (but still skilled, mind you), he has major problems. It's an eye-opener. I don't want to take credit away from Gus, I'm sure he trained his ass off, but when you look at both fighters and how well the did in their past fights respectively, one guy clearly dominated, often without getting hurt in the process.
That tells me if he moves up, legs filled out or not, many HW's would wreck him. Especially if that was the extent of his striking defense, turning your head away AFTER getting struck and displaying next to no footwork. Yikes...
