Is Jon Jones what ‘Greatness Is?’

In hyping up the UFC 145 championship bout between Jon Jones and Rashad Evans, the UFC has started a campaign called, "Greatness Is." You may have seen their ad with Evans talking about why he pushes himself to fight. Now, they released this video of Jones showing what greatness is.

Note: Lyoto Machida and Quinton Jackson both defended the light heavyweight belt since Chuck Liddell. Nonetheless, Jones' quick ascent to the top of the 205-lb. heap has been impressive. Will Evans stop him on Apr. 21? Tell us in the comments, on Facebook or on Twitter.
