Anything can happen in an MMA match and that's the fun of it, but if Machida wins ppl could arguably add Dan Henderson to the list of tailor made opponents and still dismiss Machida improvements as a fighter, as if he woudn't have a TV set at home to figure his opponents out or a camp to work on his own flaws... His victory over Couture was expected, but the way he did was outstanding and became iconic in UFC. Sacrilege to suggest that was not impressive.
Machida is by far the most complete martial artist compared to Hendo and one of the best strategists in the game, what sometimes produces boring fights, I reckon. Bader is a wrestler with KO power. This is basically what senior Hendo became today. Machida is not Bisping.
