Qawi knocks him out. Qawi's prime was at 175, but he was a ****ing monster at cruiser weight, and went to a disputed SD with Hoyfield in their first fight when he was past it.
It would have been a very good fight but I think Qawi would have been able to push Adamek back and outwork Adamek and punish him to the body, a late knockout if it were a 15 round fight, a clear decision in a 12 round fight.
Qawi, most likely by knockout. Adamek is very tough, but he'd be facing a brute who knew how to use his small stature to his advantage. Qawi would wear him down and out in the late rounds.
