Don't do it, Juan.
After landing the signature win of his career—nay, the signature knockout of his career—finally stopping Manny Pacquiao in the fourth installment of their epic rivalry, the question on everyone’s mind is a simple one.
Who’s next for Dinamita?
Many have called for Marquez to get back into the ring with the best pound-for-pound fighter in the world, Floyd Mayweather Jr.
The payday would be lucrative and the interest would be tremendous.
With the chances of the much-clamored-for Pacquiao vs. Mayweather fight almost nonexistent thanks to Marquez and his powerful right hand, it makes sense that Marquez would step in to fill the void.
But it's a fight that Marquez needs to avoid at all costs.
He tried his luck against Mayweather once before, losing a unanimous decision back in 2009 at the MGM Grand in Las Vegas. Per BoxRec.com, the judges' scorecards weren't close: 120-107, 119-108 and 118-109.
The fight itself was even more one-sided than the scoring, as Mayweather dominated throughout.
On the rare occasion that Marquez landed one of his powerful overhand rights, it brought a smile to Mayweather's face. Mayweather was simply too fast, too solid defensively and too technically sound for Marquez to defeat.
That was three years ago.
It's true that Marquez is a better fighter now than he was then—he’s bigger and stronger than he’s ever been, and his epic bouts against Pacquiao have served him well.
Who should Dinamita fight next?
But Mayweather is the superior boxer.
He's still a better defensive fighter than Marquez, and he's most definitely still quicker than Dinamita.
We only need to look back to the first two rounds on Saturday night to see that Marquez still has trouble against quicker fighters.
While Marquez held his own, Pacquiao was ahead on nearly everyone’s scorecards after two rounds because he was constantly moving.
It was when Pacquiao stopped moving that he got himself into trouble.
Mayweather never stops moving inside the ring.
Whether Marquez gets back into the ring with Pacquiao for the fifth time, takes on someone like Yuriorkis Gamboa or rides off into the sunset, he cannot allow the incredible high that comes with his brilliant victory to cloud his thinking.
Floyd Mayweather destroyed Juan Manuel Marquez once.
If presented with the opportunity, he'll do it again.
