PacMan has definitely lost a step or two in the last few years. He’s certainly not the Manny of 2005-2009, that’s for sure. Back then I’d have bet the house on the pacster, but since he’s now 75% of what he used to be, and has lost a lot of his power as evidenced by his failure to kayo anyone in the last several years, I think Mayweather wins this easily. 5 or 6 years ago it would’ve been a super fight, but now it’s nothing more than a glorified clubfighter bout.
