There are loads of interesting fantasy matchups passed around the forum here, but I don't recall this being tossed out around. This would be staged at 126 over the course of 15 and presumably the best of a two- or three-fight series, if one believes it would be necessary to make a concrete determination as to who was better.
Pedroza would be to skilled, to quick, and to physical for Marquez (It's dirty when you get caught) Pedroza should win a convincing Dec.
