The fact Pac is a southpaw triples his chances alone compared to most of Mayweathers opponents mentioned..

But Taeth is right about Mayweathers defence making ANY output fighter look slow and inaccurate.. He is possibly the best fighter of any era at nullifying his opponents offence..

It's Pac's angles and stance that hold him in decent stead...

The question is whether he can win enough rounds... Like Cotto v Margarito.. Cotto won a lot of rounds simply from landing meaningful counterpuches and having better ring generalship.. Mayweather is the best in the business regarding that. 10 times better than Cotto...

Roach would just need a gameplan to win rounds... The rest after that would be gravy.,
