Dirrell's the fastest guy in boxing north of 147 probably and he's got some skills but he can look a bit harried under pressure and I'm not totally sure about his stamina or chin. I've said this before, bit of a broken record, but I'm not sure what will happen, I could see Dirrell actually dominate Froch, I could see him have a good start but fade and get KO'd or maybe he just totally isn't ready for this kind of stage mentally.
