Also (from that article), more proof that Rios has the lowest IQ in boxing:

“I’m more than happy to do it right away,” Rios said regarding the Gamboa fight, which is the only option at lightweight keeping him from moving up to 140 pounds. “I want to prove myself and show everybody I’m not a fluke, like everybody thinks I am. I’m fighting all these guys they’re saying I’m bigger than. I need to prove myself, so I need a serious challenge.”
I know -- I'll fight someone from two divisions below me!
