It would be safer to step in the octagon with a UFC Heavyweight than follow my tips of late.
But $1.27 for Floyd would be like getting $5.00 on Winx at WFA over 1600m.
McGregor cannot beat Floyd at boxing. He will have to headbutt or break a limb in a clinch to injury Mayweather then maybe - McGregor can come over the top of a defenceless Mayweather.
But most likely scenario is that Mayweather knocks out Mcgregor - and very early as well. Because Mayweather hits plenty hard and from what I have seen McGregor is as slow as **** with very poor defence.
