Its ashame Frank didnt live up to his potential, he could of been a true legend of the sport, i know a lot of people do consider him a legend but he he had way more to offer imo. I mean what was he doing during 2000-2006? those were the golden years of MMA and thats when he should of been in his prime, but he didnt even fight. If he had stay around in those years theres no doubt he would of been in the same class as the Liddel's, Couture's etc right now.
The guy is a legend, sure he isn't that well known to the TUF noobs, but he was the first cross trainer and really did change he sport more than anyone not named Gracie.
