UFC 101 is coming with an interesting fight between B.J. Penn and Kenny Florian. Both of the fighters are very talented but the fans are leaning towards Florian as the favorite. Probably he is the favorite because his great performance in the last editions of these kind of events in which he had defeated all his opponents. We can recall the fight on April 5th, 2007 in which he defeated the Japanese fighter Dokonjonosuke Mishima via rear naked choke submission. Definitely that was his comeback after a previous loss.
After that in July 7th, 2007 at the UFC73 he fought Alvin Robinson winning by submission due to strikes in the first round. Then he won against Din Thomas via submission due to a rear naked choke. Following that fight another win against Joe Lauzon at the UFC Fight Night 13 by TKO due to strikes from mount early in the second round. Next was his winning against Roger Huerta in August 9, 2008 at UFC87 in which he won by decision (30 to 27).
In this fight he was close to losing, but a little difference was on his side. The most recent win, was against Joe Stevenson by a rear naked choke submission in the first round at the UFC91 on November 15, 2008.
We can see that Florian’s main menu is the rear naked choke. So, all his opponents have to stay away from that winning move. This has proven to give good results for Florian. With the last win Florian established himself as the #1 contender for the Lightweight Championship, and that is why he decided to fight against B.J. Penn. Actually he said: “I want B.J.'s belt. B.J., you're one of the best fighters out there. I'm here to test myself. I think you're a great fighter, someone I look up to. I consider you a master. It's time to kill that master".
On the other hand, there are people that consider that Penn has a better cardio condition than Florian and that having a better cardio condition can define who is going to win after a while in the fight. Penn is a great fighter that is going to put up some competition to Florian and hoefully Florian does not retire from the fight with a big disappointment.
