The only chance Adamek would have would be to hope Lewis came into the fight unprepared and unfocused and was writing the fight off as an easy win over vastly inferior opposition - which Lewis was prone to do from time to time - but even then Adamek would only have the opening few rounds to catch Lewis before Lennox wakes up and beats him to a bloody pulp.
So we have a Prime Lewis, versus a not prime Adamek? Since Adamek was in his prime fighting between LHW and Cruiser. Either way it wouldn't matter. The worst shape and past prime Lewis would have canceled Adamek's day completely. In fact I bet right now without a training camp he could step in the ring and stop Adamek.
