Which fighter underachieved the most in his career?

MARK KERR. At one time was considered unbeatable.

 

BJ Penn...always BJ Penn

 

Its a strange situation. He could have achieved so much more but with how late he started and the diverticulitis he probably maxed out his potential. Ah if only Inoki had managed to sign him for New Japan

 

Melvin is putting together the puzzle with Greg Jackson, he's still a young guy. The J-Lo loss was more of him falling into his own hype and taking Joe lightly.

 

not to mention a glass jaw

Note to self: Getting caught off balance = glass jaw.

 

High performance engines don't run very well on unleaded petrol.

 

Im gonna make a very bold statement ref Guillard , i do beleive he will be a UFC LW champion

Back to the original point , for all the great things he done , and as a massive massive fan of the man , i felt BJ Penn should of done a lot more , so i have to go with Penn :|

 

I'm going to make another one. He won't.

 

Well thats not really a bold statement now is it :huh

 

Paulo Filho: I know he was WEC MW champion but he could have accomplished so much more.

 

Without his steroids Filho was a nobody. Dude was soo overrated. And those Mike Tyson tattoo's looked ridiculous. That dude hasn't got any more than a few stoppage wins.

 

Yeah he was overrated but anyone that can make Chael scream like a little ***** is alright with me.

 

Mirko Crocop--one of my favorite but aside from the grand prix tournament that he won in pride, he has never held a pride fc or ufc title belt.

Of course part of it was fedor being so dominant in pride and big nog but with all the talent he had, i thought he could have at least won a heavyweight title.
