He doesn't even have a chance of getting a fight with the P4P king. He has no experience at WW, his last fight was at 135 in April of 2011 against a now shot Katsidis, and nobody knows who the hell he is besides boxing junkies.
I give him a shot at PAC and Bradley... but IDK about Mayweather... you can't outbox Mayweather maybe if you fight like DLH but never know Guerrero is a southpaw... the only one I give a shot at beating MAY is by fighting in an agressive and smart manner and being bigger then him... and being able to take a punch. I would have to see him ffight aydin...
and Bay Area Peeps.. Robert G gets KOed.. By Floyd.. I can tell you Floyd doesn't even know Robert Guerrero name..
Guerrero gives him a better fight than most will acknowledge. He's mentally composed in the ring (unlike Ortiz) but will come up short on skill/talent (like Cotto). He'd go the distance and have success in spots (en route to a wide UD loss).
..he is an unknown commodity at 147. I doubt he'll make the leap from 135 to 147 as seamlessly as Mosley did.
