We can speculate an imaginary fighter but honestly Floyd has maybe 5 to 8 fights left in him, and i don't see anyone that's in boxing or on the horizon beating him. That's not to say he is unbeatable, far from it, say he brakes his hand, very possible he can lose, just not likely, he comes in tip top shape for every fight and is never off his game, other than a freak accident, i think he rides of into the sunset undefeated and easily top 3 fighters of all time.
