I think that he beats Alexander if he can manage to connect a few good shots and tear Alexanders will to foight from him...If he can not land the shots needed to do so he gets outboxed after some close calls for Alexander....

Maidana would be a good fight as Marcos bangs like Rios but IMO just a bit harder....Would be a close call...Though Maidana has bveen in with better comp for sure..

Ortiz I see playing out like I stated the Alexander fight would but I think Ortiz folds quicker he is not as skilled as Alexander or near as fast....

Bradley breaks him down and since Bradley gets stronger as the fight goes on and Rios is so one dimensional it becomes very one sided after the 6th with Tim scoring a lop sideded UD..

IMO Khan gives him the biggest problems...The speed added with power beats Rios into the ground I say Khan is the only one I can feel confident in stating stops Rios....

Rios is a strong kid who has heart and power but as a boxer is very limited so has his comp thus far....Peterson just gave up and looked for the easy way out and he was just too strong for Acosta who when you look at his record has not been in with the best available either...

Rios has a long long way to go before he is ready for the best at 140....This kid could make 147 easy and do it in shape but his skillset would make him nothing more then a journeyman there
