Floyd Mayweather (43-0, 26 KO) needs to fight again this year and Amir Khan (26-2, 18 KO) is his best bet.
While Mayweather fights as a welterweight (147 lbs) and 25-year-old Khan competes in the junior welterweight (140 lbs) division, there has been talk for years about their eventual matchup.
Khan has promised on numerous occasions that he would move up in weight, but a loss to Lamont Peterson (30-1-1, 15 KO) put those plans on pause.
Recent drug test results however found Peterson to have taken synthetic testosterone, which invalidates his victory over Khan.
Khan now faces WBC junior welterweight champ Danny Garcia (23-0, 14 KO) in July. He is young and undefeated. If Khan beats him impressively, the stage is set.
At 35 years of age, Mayweather has not been down to 140 since 2005, but Mayweather barely re-hydrates even a pound after a weigh-in.
Most fighters go to the official weigh-in on Friday at 140 or 147 and then ascend to 150-155 on fight night after re-hydration.
Mayweather would only have to do what every other fighter has done before him and cut weight a little earlier and a little harder. It will not hurt him, but it can be used to sell this fight.
The media will exaggerate the challenge of Mayweather cutting weight to reach 140 as well as questioning how well will Mayweather perform after coming out of jail in August.
Zab Judah (42-7, 29 KO) has a very similar body-type to Mayweather. Judah went up to 147 and experienced some success and some failures before moving down to 140.
Judah is just as healthy if not healthier at 140. The main difference is his competition, which are more wet-behind-the-ears fighters like Vernon Paris (26-1, 15 KO) and not Mayweather.
Mayweather already went up to junior middleweight (154 lbs), a division he is far from comfortable at, to beat a future Hall of Famer in Miguel Cotto (37-3, 30 KO).
Shedding a couple pounds to face a less-experienced foe would not be as big a challenge as the media will likely hype it to be.
On the fifth anniversary of the year he defeated British superstar Ricky Hatton (45-2, 32 KO), Mayweather could face and defeat an even younger British star in Khan.
Mayweather has already proven he has a love for nostalgia this year.
He moved up to 154 lbs for only the second time in his career to face Cotto on May 5th, the fifth anniversary of when he faced Oscar De La Hoya (39-6, 30 KO) in his 154-pound debut.
Mayweather improved upon his 2007 154-pound win by facing an opponent who was four years younger than himself and coming off a great win.
He could also improve upon his his 2007 win over Hatton if he moves down to 140 this December 8th instead of bringing a fighter from 140 up to 147.
The fact that during Mayweather's brief stay at 140, he knocked down or out every opponent he faced there. The media will question if that exciting version of Mayweather will show up again.
All around, Mayweather vs. Khan happening at 140 makes all the sense in the world, in terms of both money and legacy. Only time will tell if it actually happens.
