This past Saturday in Denver, CO, the Jon Jones era officially began.
Over three rounds, Jones used his sizable reach advantage to keep Quinton "Rampage" Jackson at a distance where he was unable to land his bungalows.
Then in the fourth round, Jones got the fight to the ground, secured a rear-naked choke, and that was all she wrote.
Also on the card, Josh Koscheck may have sent Matt Hughes into retirement when he scored a TKO victory with just one second remaining in the first round.
There was also a pair of lackluster heavyweight duals, and Nate Diaz followed in his brothers footsteps when he submitted former Pride champion Takanori Gomi.
Now, despite whether they left the Octagon with a win or loss, how did each fighter on the main card perform?
It's once again time for the unofficial official professor of Bleacher Report MMA to dish out grades to all the main card fighters.
