This is what worries me going into the Diaz fight. Believe me, I think Anderson is the superior fighter on almost every front, but while I was initially leaning toward making a heavy bet on the Spider at -400 odds (which is past the point of wise betting on a favourite [which I put at around -333], but nevertheless) the more I think about it, the less sure I am.
Not to take anything away from Weidman's power and ability, but the two strikes that downed Silva were not connections that I would usually expect to down an opponent, let alone KO him like the first one did. The first one, the famous one, caught him weird, but he was out of it before the follow up. It didn't look that hard to me and while I don't think the fight was thrown like some idiots, I do think a lot of other fighters would have been considerably less fazed by that blow. The second one, in the second fight, was in the clinch, and not much of a power strike. The clinch tends to take a lot of torque out of punches too (just ask Alveraz after landing a dozen head shots on Cerrone), yet Anderson's eyes rolled up in his head and down he went, although he managed to survive.
Aging is one thing that can really undermine a fighter's chin and I'm wondering if that isn't a factor in what is going with Anderson. Lyoto took shots that looked way harder and came through.
Anyway, I wouldn't be surprised if Anderson lighting KOs Diaz, but if Diaz can force even a couple brief exchanges where things get a bit sluggy, I could see him clipping Anderson and shocking everyone. Am I out to lunch here?
