Dave Meltzer says there is no viable, big-money alternative to Lesnar-Mir III:
Roy Nelson is in the middle of a legal situation… Shane Carwin, recently underwent major back surgery and is out of the picture.
(Brock) Lesnar knows it simply would not be cost effective to be in a match against anything but a top star. This eliminates the next level of fighters like Cheick Kongo, Ben Rothwell and Brendan Schaub. Mirko “Cro Cop” Filipovic …is at best a last-ditch desperation name.
This leaves only Antonio Rodrigo Nogueira. But Nogueira is nowhere near the draw Mir would be. But second, … if Nogueira wins, a (Velasquez vs. Nogueira) rematch would be a tough sell. Worse, if Dos Santos wins, a Nogueira-Dos Santos title match would be almost impossible to make, given that Dos Santos is a personal protégé of Nogueira.
If (Frank) Mir beat Lesnar, matches against Velasquez and Dos Santos are not only fresh matches, but also Mir’s ability to sell a fight would make them bigger than any other potential heavyweight matchups on the roster except one with Lesnar.
