Floyd (Money) Mayweather vs Conor McGregor
August 26th 154 lbs with 10 oz gloves
My pick... hands down winner Mayweather
Mayweather 5' 8" 147 lbs 49-0 26 by knock out - age 40
McGregor 5" 9" 155 lbs 23 wins 18 by K.O. - age 29
While I have never cared for Mayweather, he is way too ring savvy to be hit and is a great great counter puncher
McGregor lacks experience with the bigger 10 oz gloves
Why it could be a good fight... age, size and strength all favor McGregor
Mayweather is coming out of retirement and his last fight was almost 2 yrs ago 9/12/15 so there is no way of knowing
how rusty he might be... He started his career 25-0 with 20 wins by knock out before age 24 fighting as a 130 lb featherweight The last time Mayweather ever knocked out an opponent was 6 yrs ago 9/17/11 so he no longer has the power of his youth, even then the vast majority of his knock outs were against little 127-130 pounders not men as big as McGregor.
Mayweather has never won a pro fight in August

(To be fair he's never had a fight scheduled in August)
My prediction: Unless Mayweather can open a cut on McGregor it goes the distance and Mayweather wins on points
in an Unanimous Decision. I don't expect the score cards will be close something like 118 - 110
I'll be rooting 110% for Conor McGregor... but I just don't see it happening.
