Atlas says Conor McGregor was ahead after four rounds of Floyd Mayweather fight.

CONOR McGREGOR led Floyd Mayweather after four rounds of boxing, said Teddy Atlas, a boxing trainer.

McGregor, a MMA star, crossed codes in August 2017, making his professional ring debut. He was defeated in ten rounds in the first round by Mayweather, an ex-pound-for-pound king.

The UFC lightweight champion at that time, the Irishman, however, was quick to get off to a good start.

Atlas, who was working as a pundit on the fight, had him up at half-way. Mayweather eventually caught up with him.

In an interview with The Schmo last summer, he stated that McGregor was ahead of him.

"I know that you guys are going choking on the pecan pie you're eating right now, but he was ahead after only four rounds.

"I was there to call the fights on ESPN, and I was there along with Chael Sonnen, who was ringside. He was ahead after four rounds."

McGregor was McGregor. There's a reason he did that: because he was reaching out.

"He's a Southpaw, he has long arms, and he's counter puncher. He was outside counter punching, using the reach of his jab, and staying outside.

"He was ahead after four rounds. Then, Mayweather did his duty in his arena to bring him down and he succeeded.

"But, the point I am making is that styles make fights."

Atlas claimed that he was wrong, but only one judge agreed with him. The other two judges had Mayweather, 45 leading the fight in three rounds to one after four.

McGregor, who is 34 years old, was granted special permission by UFC to fight the boxing legend.

Many other UFC stars have also flirted with the idea, including Kamaru Usman (welterweight champion), 35.

Usman, who has previously called out Canelo Alvarez (32), boxing's best pound-for-pound fighter, has been warned by Atlas against switching codes.

He stated that he has physicality and strength. He's also a good puncher and striker. However, I believe that a lot his strengths lie on the mat because of his knowledge and physicality.

"You can throw him in there along with a B-level or good journeyman guy. No.

"I don’t want to upset anybody with the fans out there but as long as the rules of boxing are strictly followed, he would not be able have tremendous success there."
