Now that the spectacle of the four city press tour, which saw Conor McGregor use racial slurs and Floyd Mayweather Jr. flaunt his money is over, we can look forward to the actual fight.

Mayweather (49-0, 26 KOs) will end his 23-month retirement on August 26 to face McGregor at the T-Mobile Arena in Las Vegas in a scheduled 12 round boxing match. This could be the highest grossing event in pay per view history. It will also be the biggest mismatch in pay per view history.

Could you fathom LeBron James losing a one on one basketball game to an NFL player playing basketball for the first time? That’s essentially what Mayweather vs. McGregor is.

As great as McGregor is in the octagon, he is completely out of his element in a boxing ring. The difference between competing in an MMA fight to boxing is night and day.

For one thing, McGregor is used to fighting five, five-minute rounds as opposed to 12 three-minute rounds in boxing. Then there’s having to fight with boxing shoes as opposed to fighting barefooted.

The biggest difference, of course, is that you’re allowed to kick, knee and grapple with your opponent in MMA. This will be the biggest adjustment McGregor will have to prepare for as his muscle memory will have him wanting to kick and grapple.

McGregor is a hard puncher, evidenced by the fact that 18 of his 21 MMA victories have come by knockout. However, those were with four-ounce MMA gloves, not the 10-ounce boxing gloves he’ll have to wear. So his punches won’t have the same impact.

Bottom line: McGregor couldn’t beat any of the current top 10 welterweights or junior middleweights in the world, let alone Mayweather, who is one of the greatest boxers of all-time.

It’s not just the fact that Mayweather is undefeated, it’s the fact that he’s seldom been in a competitive fight. Punch stats show that he’s the most accurate puncher and the most difficult to hit in the sport. McGregor will be fortunate if he’s able to average five landed punches per round.

Even if McGregor were to land a hard punch, Mayweather has one of the best chins ever as he’s never been knocked down by a punch in his career.

Those who believe that McGregor has a shot of winning because Mayweather is 40 years old are wishful thinkers or just hate Mayweather. Floyd has kept himself in tremendous shape during his 23-month retirement, and although he’s admitted that he’s not the fighter he once was, he’ll still make easy work out of McGregor.

This will be the easiest nine-figure payday that anyone has ever made. The only question is this: Will Mayweather knock out McGregor early, or will he look to punish him and drag the fight out?

We’ll all find out on August 26 in what will be the biggest spectacle in combat sports history.
