Manhandling is a term that suggests the manner of defeat, and yet you say that you don't care about the manner but the results. The old guy failed, that is the result, but he fought well. He wasn't defeated without forcing Guin to draw his sword, and Guin obviously fought his best to defeat him (just look at his face).
What I am saying is simple. In fights of this level, sometimes, one move decides the winner. That doesn't mean that the skill level is drastically different, which is what manhandling implies.
