The primed 175lb verison of Charles in that awesome performance vs Czyz would take Froch apart and beat him brutally. The old guy at 168 probably loses, but gives Froch issues and a real fight with that aggressive style, just as Glen Johnson did.
I am relying on the Johnson-Froch fight.Prime Williams would put a lot more pressure on him and up the punch output. Carl is not very effective on the insight. WIlliams would probably wear him down and stop him late. I have great respect for Carl who always foght the best out there but this particular style match up does not suit him well.
