I think, Provodnikov didn't leave everything in there. His face was swollen due to the many shots that scathed his face, but let's remember, it's Bradley. Dude is a V6 Camaro or Mustang. All muscle and no pop.
I think if anyone left a lot in the ring, it was Bradley. Dude took a beating all over the place and some how pulled it out of his a$$ to get the decision. Provodnikov left his workout/energy in the ring, but I don't think he's completely battle worn after that.
