IF he beats Rios which is a BIG IF, I say go back to 126 and fight Nonito But I dont see him winning no way no how.
if gamboa beats rios i would like him to face donaire gamboa would beat broner who struggled against de leon
if he wins stay at 135 a broner fight could be possible he mite move up by the time there fight is over. if no broner there is alot of good fights for gamboa at 135
