Ranking Georges St-Pierre's UFC Title Defenses | News, Scores, Highlights, Stats, and Rumors

BJ Penn is a tough man to finish. 

He has never been knocked down or submitted in professional action, but GSP finished his night in a better, even more humiliating fashion at UFC 94: He forced him to quit. 

I'll be the first to admit that I've never competed in a cage fight. I've never stood toe-to-toe with another man in a fight to the finish. 

That said, I have thrown myself into competitive environments time and time again in my life, and to force an opponent to quit is, in my experience, an accomplishment of the highest order. 

That says you broke them. Perhaps they could have continued, but they didn't want to. 

They had enough. 

On the biggest night of his life, Penn quit between Rounds 4 and 5 to avoid further damage at the hands of GSP, and this feat is remarkable. 

MMA fighters are insanely tough individuals cut from an irregular cloth, and GSP forced an elite-level mixed martial artist to throw in the towel and to flush his dreams away. 

Incredible. 

The welterweight king has never looked better, and his bout against BJ Penn will forever stand as an example of one of the sport's greatest athletes fighting at his peak ability. 

It was a thing of beauty, and it represents a brighter time in GSP's illustrious career.
