Either Belfort or Mighty Mouse
I have to go with Vitor, he's on a real tear, but only just by a slight edge. I think MM gets a very close second.. I don't know if the lawler vs hendricks fight is supposed to be this year or not.. but if it is... i think lawler could bring home the title "Fighter of the Year"... I think weidman makes a good case too if he beats silva for the 2nd time.
If Chris Weidman beats Silva again. he should be fighter of the year bar none. that simple.
I think that Rousey is kinda in the postion that Royce gracie was in way back in 93, 94. «««shes ahead in her field with her judo experience and has good power to lock on those armbars. to me getting caught in an armbar is an amature move. which proves my theory of he getting a billion in a row. she is a one trick pony. just me. Plus I this she has mental problems. go tate.
