Who would be the agressor if Mayweather fought Lara?

[SlySlickSmooth]

Floyd would likely get ahead on points and knowing it's a Las Vegas fight, Lara would be forced to become the main aggressor.

However I think Floyd outboxes Lara in the pocket with short and quick shots. Upper body movement from Floyd would make Lara miss as Floyd racks up points.

Mayweather would do his usual
Start by standing just out side of range and use his fast jab, as he racks up the points he would turn to his footwork and pick off the shots against Lara and staying well away, Lara would then have to be the aggressor to try and get points n fall into the Mayweather trap...
So to speak...

Mayweather will make Lara initiate. He will shoot those jabs to the body. Rack up points in increments like that. If Lara doesn't want to give away that round then he has to initiate.
