I watched a few Rios fights yesterday.

Anyone seen many fights of Miguel Costa? He lost b4 & quite few times since Rios, but he seemed a decent boxer to me (against Rios)
He put puches together pretty good & had some pop to his shots, but Rios pressure was relentless.

I wonder if Rios is one of those guys who needs a certain style to make him look good.
While I liked Anthony Pederson I felt his best game was inside-this worked to Rios advantage when they fought.

The last fight I watched was Rios -Urbano Antillon- quick and brutal war. But again: This was an inside fight.

If a fighter can make Rios extend his arms, stay mobile Rios is a compromised-He doesnt seem to cut the ring off well and ends up following his foe instead.

I think Rios is still a good fighter, but the style of contrasts will ultimately determine how good/bad he looks.
