Brock Lesnar was last seen inside the Octagon in December 2011. After losing back-to-back fights, he called it a career and returned to WWE.
Since his exit, there has always been speculation about a potential return. It is most certainly not likely, but there is little doubt that the UFC would benefit greatly from his return. He draws considerable interest, and his fights are the most marketable in all of UFC.
Lesnar's return would be massive for everyone. The biggest issue with a return is the lack of heavyweights to go opposite him. Lesnar showed in his final couple bouts that elite strikers capable of takedowns are not the best way to go, but Lesnar must be placed against someone credible by the same token.
That makes the list of potential fights very small in today's UFC heavyweight division. It is shallow on potential stars that would make for a pay-per-view quality fight against Lesnar.
From the talent pool, here are five men who we would love to see stand opposite Lesnar, should he make a surprise return to the sport—even if for just one night.
