This is the fight that might produce Mayweather's next opponent. Khan was a frequently mentioned potential opponent last fall before Maidana's dominant performance against Adrien Broner in December bumped the Argentinian to the front of the line.
So a dominant win on the undercard for Khan this Saturday could earn him his golden ticket in the Mayweather sweepstakes. Khan has suffered two devastating losses by stoppage in his career, to Danny Garcia and Breidis Prescott, but he is one of the few fighters in the division with speed comparable to Mayweather's.
When 2014 started, nobody would have been mentioning Luis Collazo and Floyd Mayweather in the same sentence. But last January, Collazo jumped all over former Mayweather opponent Victor Ortiz and knocked him out in two.
Another upset win by knockout on Saturday night could make the longtime veteran a sentimental favorite for a big payday against Mayweather. It's unlikely such a fight would be remotely competitive, but nobody else has been competitive with Mayweather in a long time.
In terms of a matchup, this fight is interesting. Khan is the younger man who should be in his prime, but he's struggled the past couple of years, even when winning. Collazo has seemed to be on the downside of his career for a while now, but he enters this fight coming off a thrilling knockout win.
