Pac is a gentleman, great rolemodel and a really good ambassador for the sport. You never hear any trash talk from the guy..... ever!
You can't deny Floyd's draw power outside of the ring, but inside, PacMan is just the more interesting fighter. Who represents pro boxing better? No easy answer. Ali never was your Tyson type of killer or a Morales type of warrior, but still remembered as The Man, mainly because he created so much controversy outside AND performed inside. Floyd performs, but vs. carefully selected opposition, whereas PacMan, a likeable but not really charismatic guy (or limited because of his english), but a furious, exciting, brave warrior when the bell rings. Pac represents boxing better for fight fans, Floyd represents it better for the general public.
Pac is a far better representative of the sport. I believe this is the consensus; very few seem to dislike the guy and I've yet to hear someone say they hate 'eem. He always conducts himself well both in and out of the ring. Gayweather promotes and sells fights so well largely in part because everyone wants to see the ***** get beat. Floyd just realizes bein' an ******* and talkin' **** sells tickets. This hardly makes him a fine representative of the sport.
Pacquiao of coarse. He has a better resume for start, he is a great guy, he comes to fight and brings the KO.
Resume as well, you're right. And he produces better fan-friendly results and when he fails to win by KO or something clearly decisive he doesn't throw out a fat-ass book of excuses for why he didn't.
Mayweather does not close the show either. GREAT fighters close the show, its a very important part of being a truly GREAT fighter.
