The key here is, Pac don't want to get KO'ed anymore. Knowing Mayweather is a better counter puncher than Marquez, stronger, faster and smarter. He never wanted to take that chance. He was hesitant all fight giving Mayweather to much respect. He only threw flurries when Mayweather was in the corner. Never did it in the center of the ring. He knew better! Very slow fight, but Mayweather controlled the pace, that's what he do, which he won a wide UD. Just except it. Mayweather is the best fighter in this era!
