LAS VEGAS -- The previous two bouts between Manny Pacquiao and Juan Manuel Marquez offer ample opportunity for in-depth analysis of Saturday's fight at the MGM Grand. The strengths and weaknesses of both fighters are evidenced in the extraordinary 24 rounds that already have been disputed between them, and it's clear even after the years that have passed since then that many of those traits have held up over time and will play a key role in the outcome of the fight ahead.
When they met both times years ago, the fighters appeared evenly matched in key areas, but over time Pacquiao has grown (or at least maintained his skills) more than Marquez in most cases. Based on that assessment, it seems Marquez will have more trouble trying to look good enough to clinch a points victory. Pacquiao has plenty of tools in his bag of tricks, but to beat Marquez he will likely have to use some combination of these five features:
Bigger is better
Settle the score and move on
Anything you can do
Power, power, power
Time on his side
