If and a big IF he KO's the ghost, I still dont think floyd will take that fight. Not a cedible win for him really. He lost bad to Ortiz, Floyd smash Ortiz, his fight with janvek is not berto best and was stopped cause of a head but, then a long layoff, Berto had some darma with testing, and IF he KO's guerrero doesnt really mean much cause people will say the ghost didnt even belong in 147 so he will get no credit for that win.
I think Floyd fights Bradley next. Easy fight to sell as the last person to beat Pacqauio and its a fight floyd can win. and since bradley fought pacquaio ppv buyers will reconize him as a credible fighter.
