After watching that footage, the 63 year old Mayweather Sr. - who was once a pro himself - believes he has enough left in the tank to beat McGregor quiet easily in a boxing match. "But I've no problem going and slapping the head off one of his opponents that he couldn't finish".
"It's a joke for boxing if (Mayweather vs McGregor) happens", he said to Reuters.
Making the transition from MMA to boxing, and doing so against the best fighter of his generation, McGregor would have little to no chance of leaving the ring with a win.
As the biggest name in the UFC, McGregor headlined three pay-per-views in 2016, which likely generated close to four million total buys.
However, Alvarez, who suffered his sole defeat in 50 fights when he was outpointed by Mayweather in 2013, is not sold on a showdown between the pair.
Reports last week suggested terms had been agreed between Mayweather Jr and McGregor.
Well according to McGregor, who spoke briefly with TMZ this weekend, he didn't talk to Mayweather at all and instead chose to take a few more shots at the retired boxer as they continue to banter back and forth in the media while trying to put the fight together.
In his fighting career, Mayweather gained something of a reputation for dodging fighters when they were in their prime; it took almost a decade for him to fight Manny Pacquiao. Everything is pointing in that direction right now.
If the most recent comments from McGregor and Mayweather are any indication, that's much easier said than done.
"He is a pretty good striker", Roach said of McGregor.
Many fans of the UFC Lightweight champion were probably speculating that the reason why McGregor went to Las Vegas, Nevada, was to negotiate with Mayweather Jr. about the fight.
But "Money" rubbished those suggestions and called on the UFC star to make the fight. Despite having never competed in a professional boxing bout in his life, McGregor's pursuit of a superfight against one of the all-time greats is stealing Canelo's thunder. I have a lovely family, four great children and many friends that have been there since day one.
