Floyd Mayweather is the overwhelming favourite to win his fight against the Irishman Conor McGregor in less than two weeks time.

One of the greatest boxers of his generation and, quite possibly, the greatest defensive boxer of all-time; Mayweather is hoping to surpass the record of Rocky Marciano, a world heavyweight champion who won all 49 of his professional fights.

‘Money’ began his career in 1996 when he beat the Mexican Roberto Apodaca, and retired 19-years later when he outpointed Andre Berto at the MGM Grand Arena.

But a lucrative fight with McGregor has lured him out of his retirement, with his reputation now firmly on the line.

What is his fighting style?

Mayweather is widely regarded as the greatest defensive boxer of all-time. A defensive counter-puncher, Mayweather was given the nickname ‘Pretty Boy’ early into his career, because of his extraordinary ability to avoid taking damage in his fights. He hardly ever stands squarely across from his opponents and dodges a large number of punches with his famous ‘shoulder-roll’ technique.

The undefeated American is also regarded as one of the smartest boxers in the business, and possesses an incredible fight I.Q.

Mayweather typically relies more on his defense than his power, although that doesn’t mean his attack should be underestimated. A knockout is, however, unlikely: Mayweather hasn’t stopped an opponent since defeating Victor Ortiz in 2011, while McGregor has never been knocked out.

What titles has he won?

His fair share. Mayweather has won the WBC super featherweight, lightweight and super lightweight titles. He has won the IBF welterweight title and the WBO welterweight title.

He has also won the WBC welterweight and light middleweight titles, as well as the WBA (super) light middleweight and (super) welterweight titles.

He has been The Ring lightweight, welterweight (2x) and light middleweight champion.

What awards has he won?

Again – lots. Mayweather was named The Ring’s Fighter of the Year in 1998 and 2007; ESPN’s Fighter of the Year in 2007 and 2013; and Sports Illustrated’s Fighter of the Year in 2015.

In 2016 ESPN named Mayweather the greatest pound-for-pound boxer of the last 25 years, while The Ring named him the 12th greatest boxer since World War II. ESPN have also named him the 48th greatest boxer of all-time, back in 2007. Were they to update their feature, he would undoubtedly place a lot higher.

And that’s without the non-boxing awards. Mayweather topped the Forbes and Sports Illustrated lists of the 50 highest-paid athletes of 2012 and 2013 respectively, for example, and also topped the Forbes list in 2014 and 2015.
