... also, I believe Froch and/or GGG sparks Mayweather out cold. Moreso Froch.

I don't think we have been watching the Carl Froch since he made the comeback and won the title by disgracing Lucian Bute. He is a very different Carl Froch. No one, aside from WArd (more of his size and can take a Super Middle punch) is able to deal with Froch at this stage.

A Ward/Mayweather fight would be interesting, but we know it won't happen.

Floyd would more than likely take a Sergio Martinez fight and beat him soundly....

Mayweather won't want a GGG fight. Too much power and too accurate. It's not necessarily the speed, but the size and the punch accuracy- which is much better than Canelo's or anyone else in the business.
