Floyd Mayweather's Last Fight Must Be Against Amir Khan

Floyd Mayweather Jr. is now 48-0 after defeating Manny Pacquiao on Saturday in a superfight that took years to come together. "Money May" only has one bout remaining on his contract, and if he wants to end his legendary career in style with a quality win, he must take on Amir Khan.

In a classy gesture following Saturday's showdown in Las Vegas, Khan applauded Mayweather's victorious effort:

Then Khan made it publicly known Sunday that Mayweather is someone he wants to take on. Although he won't be able to meet Mayweather on his originally scheduled date in September due to Ramadan, Khan did have some insight into the situation, per AFP (via Yahoo Sports):

"

I think the fight is there [...] I spoke to Len Ellerbe, his manager, I saw him in the media room and he came over to say 'hi...he's ready when you are.' [...] I think it would be an amazing fight, one that boxing fans all around are talking about because I really believe size is a big factor between me and him and the speed and the power as well. I really believe I have his number.

"

Mayweather was the better boxer in the Pacquiao fight, yet he has been rightly criticized for dancing, dodging and ducking too often and hugging Pac-Man when he was hurting at times.

Those who defend Mayweather's style will express appreciation for his technical brilliance, strong counter-punching and uncanny defensive ability. That's fine, but he needs to keep things interesting for his grand finale.

The apparent shoulder injury Pacquiao fought through somewhat sabotages Mayweather's unanimous-decision triumph as is. Although a rematch would be something Pac-Man would welcome, it took long enough to agree to terms between the two sides in the first place.

ESPN's Skip Bayless is among those who were disappointed in the result:

Mayweather is likely to be offended by such talk, after finally agreeing to the fight that fans wanted and winning, he is now being bashed for how he won. There's little incentive to go down that road again.

With Khan there is already mutual respect, so terms shouldn't be difficult to negotiate. With the amount of draw Mayweather's star power generates, prize money won't be difficult to come by. Even Mayweather brought up Khan as a potential final opponent, per The Daily Mail's Jeff Powell.

Khan's brother brings up strong points as to how Mayweather could be in trouble if he chooses Khan as his next adversary on Twitter.

Just 28 years old, the tenacious Khan boasts a stellar 30-3 record with immense punching power and tremendous speed, which will give Mayweather's lightning-quick reflexes a major test.

The hunger Khan's brother speaks of has to be real. This is the big opportunity Khan has to establish himself as a legitimate superstar in the sport, and he may even have the goods to hand Mayweather his first loss.

Boxing might experience a hangover of sorts following the Mayweather-Pacquiao bout. If Mayweather were to risk a lot in his final appearance in the ring against someone like Khan, it would generate even more buzz and add to his legacy as one of the sport's all-time greats.
