1st 6 rounds are anyones game.
If it goes longer Mayweather will outpoint McG and cruise to a boring decision like most of his other fights.
Mayweather isnt what he used to be and hes 40 bow but even back then he was a defensive fighter, not a knockout artist.
That said, he's the best modern age boxer to lace up gloves.
McG isn't new to boxing. He boxed amateur for years, and trains like a beast, is much bigger and hits harder than anyone Mayweather has ever faced.
He can switch his stance and fight fron either side, and has a blistering left that will rock Mayweather when it lands.
And it will.
Smart money bets on a Mayweather decision.
If you can afford to lose some scratch, a bet for McG in the early rounds would pay off nicely.
Bonus:
If they actually agree to the 8oz gloves Mayweather proposed, it will be very interesting indeed.
