Agree with that... I see Machida winning... Hes footwork and speed should allow him to hit Dan and avoid Dan's shots... but of course if Dan is able to land something, he can put Lyoto out.
as far as Dan's chin goes, I dont know... I wish there was more information out there on what makes some people harder to knock out than others...
And yes, even better chins have a threshold... over time they degrade with all the punishment they take... I do see Dan getting finished in this fight, and possibly others afterwords, depending on who they match him up with... Glover would probably put him out at this point as well.
I agree with alot of what you said, but I think Glover would eat a Hendo bomb or two and go out.
