Well I know it's after the fact but I did think Hopkins would win. I know he's 39 years old, but you can only move up so many weight classes before the power difference becomes too much to overcome. Truthfully, I think most people going to the fight were either Oscar fans (of which he has legions), or the "anti-Oscars" who knew he was biting off more than he could chew and was going to get his head kicked in.
Incidentially, I'm not in either camp, and I didn't even see the fight, but I'm not the least bit surprised by the outcome either.
