How retarded are you..really? Mir won one and Lesnar won one. IF they fight again it will only be because Mir will have gotten through Congo & Carwin and to settle the score. It has nothing to do with what you're alluding, which is that the UFC has no one to put in front of Lesnar. If Mir Loses, it will either be Carwin, Nogera or Velasques that gets the shot at Lesnar.
Do you get it now, or do you need me to dumb it down even more
