Anyone who doesn't give Chael his due in the first fight is just making excuses. I'm sure they make you feel better, but delusions are delusions. Here's a fact... Sonnen cracked Silva's ribs.
Anyway, I see no problem with this. To think that Anderson isn't all kinds of special and couldn't fight well into his 40s is nonsense. People say that Couture's situation was unique, blah, blah, blah... as if Anderson himself isn't a unique fighter. He's taken very little damage. He's rarely gone the distance. His body is likely holding up better than most.
