What will a win mean for either guy? And what will a loss mean for either guy? Where will they go after? I'm assuming Carl moves up after this one, win or lose. He's massive at the weight. Frampton/Russel Jr would be a good fight. As would a clash between Carl and LSC. Scott might move up as well, but that'll be down to Rigo (same for Carl) and not weight issues. He'll probably face Selby due to that fight being easy to make or someone like Mares who would suit him to the tee.
If it as a close fight like Degale/Groves then I imgaine a immediate rematch which could even be at a catchweight like 8 stone 12lbs. If one is knocked out then it is going to be a good 12-18 months of rebuilding up at featherweight.
