Excellent article. Well written and thorough.
I think you're right, it is hard to make a case for McGregor. Mayweather wants everything in his favour from the size of the ring to the size of the gloves. Additionally McGregor has never boxed twelve, three minute rounds - and never boxed at a decent level.
However, there is always the freak occurrence. The slip, the dropped hand at the wrong time, the sucker punch.
My head says Mayweather wins in the middle rounds, my heart wants McGregor to knock him out.
Let's all hope it lives up to the hype.
