#2. Yoel Romero
Yoel Romero. A controversial figure in the UFC, and apparently, currently in talks for a shot at either the Interim or the Official UFC Light Heavyweight Title.
Competing for the title would mean moving up a weight class for him, but at this stage, that makes sense.
His recent form has been abysmal in the Octagon, and it is high time that he picks up wins once more. He has 2 losses in his last 3 fights, accounting for 2 of his total 3 losses in his career.
At this stage, him winning the talked-about fight would mean facing Jon Jones finally in the Octagon. A possible victory for either the Interim or Official Title would mean that Romero's stock would shoot straight up into the sky.
A return for Jon Jones in a fight against Romero would be a good way for Jones to show he still has what it takes to make it in the UFC.
