Is Gus still feeling the effects of the rumble fight?

[Readybodisready]

I'm not just talking about his running. It's his reactions and behavior at any range when his opponent is about to attack. It is the sight of a fighter being extremely cautious about getting hit, almost scared. Only reason I made the observation is because again, he used to be the opposite. He took huge shots to the jaw atleast once or twice in every fight before and barely flinched. Do you think the Gus of the Jones fight would have panic wrestled against Jan?
