UFC 140: With Jon Jones on Top, How Deep Is the Light Heavyweight Division?

The light heavyweight division is the most stacked division in the UFC.

But for how long?

After turning in another dominant performance at UFC 140, Jon Jones (15-1 MMA, 9-1 UFC) has run his 2011 career to a perfect 4-0 defeating Ryan Bader and three former champions in Maurício "Shogun" Rua, Quinton "Rampage" Jackson and Lyoto "The Dragon" Machida. 

Jones is still young and is still learning. With every performance he seems to improve and grow, adding new skills and techniques to his arsenal. Even when presented with adversity for the first time in his career, Jones proved he can maintain his composure and battle back to dominate. With all that he's accomplished in such a short time, who can realistically stop him?

Rashad Evans, former training partner turned arch-rival, is expected to face Jones if he can get past Phil Davis at UFC on Fox 2. Evans has inside knowledge of Jones' fight training and will likely put that to good use against the champion.

Davis, should he prove victorious over Evans, could give Jones an interesting challenge. Hailing from a collegiate wrestling background, Davis has a similar skill set to Jones and would suffer the smallest reach disadvantage of any fighter to face the young champion. 

Dan Henderson recently defeated "Shogun" Rua in his UFC return and though he started out dominantly, looked unspectacular in the later rounds. His age also plays a factor in how long he can continue to fight at the highest level.

Should Jones defeat Evans, Davis and Henderson, who is left to challenge for the title? As Jones continues to dominate his opponents he'll slowly begin to damage the credibility of his division. Much like the middleweight division looks weak because of Anderson Silva's dominance, so too will the light heavyweight division with Jones.

How many more defenses will Jones make before the once "stacked" division begins looking weak and shallow in the shadow of its dominant champion?
