After producing yet another upset with an impressive UD win over Lucas Matthyse in a fight nobody thought would last the distance, Danny 'Swift' Garcia seems a ready made opponent for Floyd next year.
It wouldn't be the first time Garcia would enter the fight as an underdog, and with wins over Amir Khan, Erik Morales and Zab Judah, he is no stranger to the big stage. While Mayweather would, undeniably, prove a huge step up, Garcia would be following a similar path as Canelo by showing off his talents on Money's undercard before taking on the man himself.
As many were quick to point out after the memorable card on Saturday night, this fight seems the most natural next step. If Miguel Cotto proved to be Floyd's biggest test in recent years, the new boxing pride of Philly could be the same. Whilst Cotto's relentless attitude probably served little more than to remind us how well Mayweather can fight off the ropes, many were left disappointed that the younger Canelo couldn't bring a similar gameplan and push the 36-year-old back.
At this stage it is becoming increasingly difficult to even sell the prospect of a potential Mayweather opponent having any chance, but Garcia's one-punch knockout power and the impressive boxing ability and ring intelligence he showed against Matthyse might make him the best bet.
Garcia's chin, and more importantly his heart, held up against Matthyse - he could be one of the few men who might have a chance of really pushing Mayweather into the late stages of the fight
The prospect of Floyd moving up to face Golovkin is a mouthwatering one, albeit unlikely. Golovkin has shown a willingness to drop down in weight to meet the Pound-for-Pound leader, but going as low as 152 is a non-starter.
Golovkin is gathering a reputation as one of the most feared fighters in the sport, and his brutal stoppage victory over Matthew Macklin showed why. In fact, only half of his last six fights have lasted longer than three rounds, and Golovkin's explosive power means none of his opponents have heard the final bell in over five years.
By taking the Canelo fight just four months after a wide unanimous decision victory over Guerrero, Floyd answered a lot of his critics by fighting the best opponent out there. Whether he would continue along this route with a fight against Kazakhstan-born fighter is questionable. There are those that will say with the win on Saturday night, Mayweather has sealed his legacy as an all time great, if that wasn't a certainty already.
At this stage in his career, iand having already moved through many weight classes, Mayweather may argue he doesn't need this fight. But what a fight it would be. For many, GGG is the biggest puncher there is, and anybody who thinks Mayweather can't be hurt need only look at round two against Shane Mosley back in 2010.
But Mayweather's defensive ability is unmatched, and with a 73 per cent KO percentage going in to the fight, Canelo was no feather-fist either, yet couldn't leave his mark on Pretty Boy Floyd.
If anybody can put Mayweather on the canvas it is Golovkin, but with his recent performances it is almost blasphemy to bet against yet another defensive masterclass that would only extend the unbeaten record.
Despite two losses in as many years, Amir Khan remains very relevant as he prepares to challenge for 147lb glory later this year against Devon Alexander. While the fighters above will boast more impressive records in recent years, a win against Alexander would make Khan a two-weight world champion.
Furthermore, for the casual fans he is still a household name, and a lucrative date at Wembley Stadium may prove tempting enough for Floyd to fight in the UK. If Floyd wants the numbers, he will take this fight next if - and it's a big if - Khan gets past Alexander in December.
How competitive Mayweather-Khan might be is another matter. Khan's speed could pose some problems to Mayweather but his style would invite some potentially devastating counters.
The winner of Manny Pacquiao-Brandon Rios
While Floyd v Manny wouldn't nearly have the same heat as it would have had two to three years ago, if Pac-Man can impressively overcome Brandon Rios on November 23, expect the drum to start banging again.
Pacquiao's stock has plummeted in the last 24 months; an unconvincing victory over Juan Manuel Marquez in 2011 was followed by a controversial points loss to Tim Bradley and a devastating KO by Marquez back in December.
At the moment, a fight against Mayweather looks unlikely but if Pacquiao can produce a huge comeback with a victory later this year, this fight suddenly becomes relevant again.
As for Bam-Bam, there are few more exciting fighters in the sport of boxing today. He provides the enthralling power but Floyd would be confident that his defensive ability and the efficiency of his straight right could nullify this.
What holds back the prospect of either of these two stepping into the ring with Floyd is his relationship, or lack thereof, with Top Rank. Bob Arum would face a difficult task in getting Mayweather in with either of his stable stars, but with his negotiating power higher than ever, money might talk for TMT.
Bernard Hopkins (The ageless light-heavyweight champion claims he'd drop 15lbs for shot at Floyd)
Sergio Martinez (Middleweight boss could be tempted by some Mayweather millions to lose weight)
Timothy Bradley (If he beats Marquez next month, his stock soars)
Devon Alexander (Not hugely marketable but a win over Khan will see his relevance increase)
Marcos Maidana (If he shuts Adrien Broner's mouth in December he will get Mayweather's attention)
Darren Barker (Highly unlikely but the promise of another title in another division could tempt Floyd)
