Nick's last fight was against Anderson Silva at 185 lbs so I think that's a yes.
Nate's last fight was at 170 lbs and he is now booked for another at 170 so he seems to have moved up as well. In competitive MMA Nate is a 155 lb LW and Nick is a 170 lb WW but they are "Needle Movers" apparently so they can have fights that truly have no meaning.
I like the idea of giving Bisping a quick turn around if he isn't hurt. Weidman, Rockhold and Jacare all need surgery so if Bisping wants a fight soon he should get to cherry pick an opponent. Nick Diaz is one choice and they could even make it a non-title fight if they wanted. I wouldn't mind giving Dan Henderson a shot at UFC gold that has eluded him while giving Bisping a chance at Avenging his UFC 100 loss. Really depends on whether Bisping wants to hold on to his belt and make money outside the Octagon doing appearances or if he wants to try and rack up a few bucks defending it. I am so happy for Bisping and thought he could KO Luke if he planted himself and threw shots but honestly he most likely loses if he defends against Luke, The Chris or Jacare.
