Steward: Small window for Pacman

[Preme]

Emanuel Steward says Manny Pacquiao will only stay at the top for another two years.

Steward, a Hall of Fame trainer who transformed Thomas Hearns among others into a world great, says Pacquiao's style means he only has a short shelf life.

The Filipino southpaw recently proved his brilliance with a knockout of Erik Morales in their rubber match.

as long as he get's to beat Valero, Guzman, Marquez and Barrera within the last 2 years or atleast Valero and Guzman. i think after that Pac doesnt need to prove anything anymore.
