I'll go with decision to Froch. I can't see AA knocking him out.
Froch has taken bigger punches from bigger guys and proved he can trade and doesn't gas.
If anything I'll be questioning AA stamina later rounds when Froch piles on the pressure.
Froch is too tall and long for AA. Froch UD....
This is kind of what I think, I haven't seen enough of abraham so I need to study him in more detail, but froch's reach is an underrated tool in his fights. He is hard to deal with becuase he often reaches fighters with shots that other smw's wouldn't, and you can tell he is very heavy handed. These maybe problems too big for a shorter smw like abraham. For abraham to win he needs to get on he inside and explode with short combinations, but he may take too much leather in the process
