Last week, Rocky Marciano Jr. - the son of legendary heavyweight Rocky Marciano - said Floyd Mayweather vs. Conor McGregor was nothing more than an "exhibition fight."

On Saturday night, Mayweather returned from a two-year retirement to stop McGregor in the tenth round at the T-Mobile Arena in Las Vegas.

The victory raised Mayweather's record to 50-0, which surpassed the 49-0 record of Marciano.

Marciano Jr. - among many others - was upset with the Nevada State Athletic Commission for sanctioning Mayweather-McGregor as an official boxing match.

McGregor, a two division champion in the UFC, had no experience as a boxer. He made his professional boxing debut against one of the finest pure boxers in the history of the sport.

After the win, Mayweather acknowledged Marciano with praise.

“Rocky Marciano is a legend,” Mayweather said. “I take my hat off to him. He paved the way for me to be where I’m at.”

Marciano Jr. has no beef with Mayweather surpassing the record - if the victory had come against a credible boxer.

But under the circumstances of the fight, Marciano Jr. feels strongly that Mayweather's record should have an asterisk next to it.

“To me, it’s an exhibition fight. I think it definitely should [have an asterisk]. There’s such a big difference from the boxing ring to a UFC octagon, and it’s such a big learning curve. Mayweather’s had an incredible career and he’s had 20 years of greatness, but I would honestly give a boxer who has come up through the amateur ranks, having his first professional fight more of a chance than McGregor," Marciano Jr. told the New York Post.

“The fight went pretty much the way I expected it to go. Mayweather would take it slow in the beginning and see what McGregor would throw at him. Mayweather knew that McGregor would tire in the later rounds. If people want to say this is breaking Marciano’s record, sure, it’s disappointing because you want to see him challenged and fight the best he could. If he wants to be the best pound-for-pound fighter of his generation or his weight class, I think as fans of boxing, we want to see people pitted against the best and then see the result, and that’s not what we [got]. There is such a discrepancy in experience. Will they say, ‘Yeah, he got it, but look how he got his 50th win?’ That’s the conversation moving forward.”
