Yep, it is a pretty small head. As far as heads go, it is a kind of SMW proportion perched on a very long, lanky frame. Will that be the difference? I could not say for sure, but phrenology is one of my interests and believe a small head indicates higher intelligence and is a sign of enhanced evolution. All these fat, big headed heavyweights are not the way to go if you want smarts, speed and range. However, they can thump pretty hard and if a small head is clubbed you can get some of the most spectacular KO's. In the film Mars Attacks, I felt the small headed aliens were presented in a mean spirited way and similarly I think Brockton might be approaching it from a Hollywood entranced angle. Sometimes the small heads can be moral, resiliant and devastating in the boxing ring. Paul Williams and Thomas Hearns are other examples of the small headed brigade. They were very good and could throw long punches and hurt people, but sometimes they could get absolutely bombed away and that gives some evidence to support Brockton's thesis. The big heads like Baldomir, Valuev, the cave troll, the rhino, and Dennis Lebedev look very intimidating, seldom get stopped, but you can outbox them as they lack the co-ordination, speed, and intelligence of the future evolved being boxer type. It should be a fun fight.
