i know that before the karmazin fight spinks said "if floyd wants to fight at 154, he should fight the best....and thats me" (or something along those lines)
then of course, after the fight spinks made a quick reference toward fighting floyd
i could see this fight happening and i think it would be a good fight, even better than margarito. seeing as how its been a goal of floyds for a long time to capture world championships in 5 different weight classes before he turns 30 (he would be the first to do so)
spinks now has a legitimate world title at 154, and looked pretty good obtaining it.
also, it would give floyd a lot of time to adjust to the new weight class before the potential mega fight with oscar next year
this is just another possibility of who he could fight next
