Canelo? He would potentially retire Khans remaining brain cell and I just don't see why any of them would be at 154 just to face him and Canelo sure couldn't do 147. Mayweather did it at the higher weight, but the fight was a bore and I would never want to see that again. Khan/Mayweather/Pac fine, but with someone else, not Canelo who has already lost at his optimum weight.
