Wandy from Pride FC? Decent chin.
Wandy now = Yes, glass chin.
That's pretty much what happened to everyone who are past their primes. (Except for Hendo at 42 years old!)
Miguel Torres is just a LOL glass chin. If you watch his fight with Bowles, look at him go out cold from pillow-powered left hammerfists. He looked like Machida when Shogun KO'd him. Except Machida's chin is better. Getting ko'd at BW is just shameful.
