Rios struggles to make 135 and I think he would be much better suited at 140, he is also more of a accumalative puncher I think, heavy handed and wears you down as the fight goes on rather than a one punch banger, Alvarado was badly behind in his last fight against Breidis Prescott, I had Prescott winning all 9 rounds before that great tenth round, I think Rios would have this fight on the inside all night long as thats where Alvarado does his best work also.
