These aren't even "official" unofficial rankings. This was copy and pasted from a thread on the sherdog message boards. Some random guy decided he wanted to rank the fighters and posted it on thier message boards, so they don't carry any wieght or meaning outside of what you want to give them.
It is a good premise for discussion though, so how about it? What would we rank each division? Someone should start up a thread for each weight class and come up with a mmaforum ranking.
