you don't think sexyama was being fed to belfort to build him up after losing to anderson?
i'm not sure how i'd define a can, but since you asked i think somebody outside the top 10 in the following divisions: bantamweight, featherweight, and heavyweight are probably cans or jobbers since these divisions are so weak. Outside the top 15 at middleweight. And outside the top 20 at lightweight, welterweight, and light heavy.
I also assume that anybody competing in Japan, i.e. in Dream, after the fall of Pride to be a can. UFC or bust at this point, it's why I don't watch the CFL when i can watch the nfl every sunday.
With that said, akiyama is totally a can, he could have been 0-4 in the ufc, he was gifted the decision versus belcher.
