If it was a completely focused Spinks...The one without his freaking entourage coming to the ring and rapping telling him how great he is.....The same Spinks from the first Judah fight...at 147 IMO it wouldn't be that big of an upset if he won....It would go the distance of course but I could see Spinks pulling out a SD.....Of course his head would get so big it would explode and Floyd would murder him in the rematch but....That is another story
