Robert Guerrero will no doubt face the biggest challenge of his professional career on May 4 when he steps into the ring with pound-for-pound king Floyd Mayweather Jr.
The 36-year-old Mayweather has been the standard of excellence in boxing for the better part of the last decade and has rarely even been challenged in the ring.
But he is coming off a long layoff and has suffered through personal trials that have forced him to take his attention away from the fighting aspects of the sport.
Could he be ripe for a young, hungry fighter with difficult and rugged style of Robert Guerrero come May 4 at the MGM Grand?
Possibly, but only if Guerrero manages to avoid making these five crucial mistakes.
