"after surveying the landscape, it appears very likely that at most, Lesnar is only two consecutive wins away from a shot at the title. In fact, he could even be granted a shot with just one more victory; there isn't a long line of UFC heavyweight contenders."
Now before you blow off the claim think about how big a Brock Lesnar vs Nogueira fight would be if he retains his belt at the New Years Eve card. Then think about how big a Mir vs Lesnar rematch would be after having the highlight on Sportscenter and Youtube of Mir tapping out Lesnar. That would be a gold mine for the UFC and would possibly bring in a new face to the UFC's heavyweight division as well. Lesnar would be the posterboy of the UFC for years to come and would make a major impact selling pay per views and merchandise as well. I personally think Lesnar's presence would usher in a whole other generation of WWE fans becoming UFC fans.
