Although I agree with you on all of your points, I think at this point in mayweathers career, he may just be that tiny bit too slow and small. I really do think McGregor could take him out. Although I still think Floyd wins by a what most casual fans would call a "boring fight".
I don't think it's a waste of time and money though, I think it will a great event. Possibly one of the biggest sporting events of all time if it's promoted well!
Thanks for the comment @toblerusse I always love to see peoples opinions on this stuff, especially my Boxing/MMA posts!
