There is 2 big things at play here. One...Pac is now incredibly confident mentally and physically. His resume is now more impressive than Floyd's as well. He has fought some great fighters in their PRIME. Something i cannot say is true for Floyd. The second thing...you cannot discount Floyd's inactivity or lack of fighting a truly great, PRIME fighter in his career. Floyd has fought big names, but Pac is at the absolute (or very close to) peak of his powers. Pac is no past it Oscar, headcase Judah, one dimesnsional Hatton, etc. No doubt Floyd is the most skilled and intelligent fighter in the business. But Pac is unlike any fighter Floyd has faced. I still think Floyd's brilliant skills, ring savvy, and preparation will make him the favorite. But i know longer think it's a sure thing he will win.
