Floyd Mayweather Jr. will return to the ring to defend his WBC welterweight championship against mandatory challenger Robert Guerrero on May 4 in Las Vegas.
Most observers expect Mayweather to have an easy time in the fight and setup a potentially more dangerous showdown with junior middleweight champion Saul "Canelo" Alvarez in the fall.
But those same observers overlook Guerrero at their own peril. This fight is a lot more competitive, and dangerous than it appears on paper.
These are five reasons that Floyd Mayweather is making a mistake in taking on Robert "The Ghost" Guerrero in May.
