I see Mayweather using the high guard the first two rounds, getting Conor's timing, range etc. Conor probably gets him the corner one of those rounds and let's his hands go and the Pro-McGregor goes wild. When they show the replay it will show all those punches we're getting rolled off Mayweather's shoulder causing no damage. Third and fourth rounds Mayweather starts hitting pot shots. McGregor missing more of his punches. Fifth and six Mayweather let's thw combos go snapping McGregor's head. By the seventh round either the ref stops it or McGregor's corner throws in the towel. Mayweather by TKO
