Benson Henderson, 29 years old (17-2)
Henderson is now the undisputed UFC Lightweight champion after beating Frankie Edgar in Japan in February to win the title. The fight was close and controversial, so the two went at it again in August, when Henderson got the decision again.
With Edgar in his rear view and the belt around his waist, Henderson will now take on the bigger and much different Nate Diaz this weekend in his second title defense.
Henderson has a power edge in the stand up game, as he throws his punches and kicks to hurt you every single time. He does give up some skill on the ground compared to Diaz, but due to his compact physique and uncanny dexterity, he has never been submitted.
Wrestling is absolutely on Henderson's side and could be the major difference in the outcome of this fight.
Nate Diaz, 27 years old (16-7)
After his brief and unsuccessful time at welterweight, Diaz is back at home in the lightweight division and comes into this fight on a three-fight win streak. His destruction of Jim Miller in May earned him his title shot and is his only fight this year.
Diaz employs the famed Diaz boxing style of punches in bunches with cumulative damage being the goal. He has incredible range at 155 and the cardio to throw all night long. His Jiu-Jitsu is among the best in the division, and he can also do damage from his back.
If there is one flaw in Diaz' game it would be takedown defense and wrestling overall. If Henderson can take Diaz down and stay out of danger while on top, this could be a very similar fight to the GSP-Condit title fight that we just had and a long night for Diaz.
