The 39-year-old Mosley started his career with a 38-0 record. Since then, Mosley has dramatically tailed off. He has posted an 8-6-1 record since, and is using this fight with Pacquiao as an opportunity to resurrect his career.

Pacquiao, 32, has been the best pound-for-pound boxer in the world for quite some time now, and hasn't lost a fight in over six years since a unanimous decision to Erik Morales. He has dominated opponents, and has the chin to take a good hit.

Both Mosley and Pacquiao are defensive-minded, counter-punching boxers, but Pacquiao will likely be the aggressor.

Pacquiao's victories against the elite of their respected weight classes gives him an edge going into Saturday. The Filipino legend is coming off four major victories against Antonio Margarito, Josh Clottey, Miguel Cotto, and Ricky Hatton.

Mosley has a height advantage of almost three inches on Pacquiao. This may help his accuracy of landing punches as well as avoiding some of Pacquiao's harder punches.

As the younger fighter, Pacquiao will likely show more speed and energy. However, one punch or one combo from Mosley can completely change the complexion of the fight.

It will be up to Mosley to throw Pacquiao off his rhythm, and try to connect on a big left hook.

Otherwise, Mosley will be in for a long night, as Pacquiao tends to go the distance and win decisions.
