I wasn't sure about it either, but this match is 100% just for our entertainment. (EDIT: In other words, they aren't designing this fight with the intention of pushing a guy or not. It's a filler match which will also be extremely entertaining. It'd be like having Rich Franklin fighting Nate Marquardt. Two guys who lost to Spider, who won't be getting another shot anytime soon. It's just there for filler, but will also be a great match.) If Brock loses, they'll think of what to do. If Herring loses, all right.
Either way, it's Nog and Mir before anything, and there will be time to build a new #1 around Herring, Vera, or Werdum. There will be challengers for Nog/Mir regardless.
Either way, I was EXTREMELY disappointed about Coleman being hurt, but now, this card is going to be so much better. GSP/Fitch + Florian/Huerta + Lesnar/Herring is better than just Lesnar/Coleman and Florian/Huerta, in my opinion.
