Losing to GGG at 160
or
Defeating GGG at 155
I MAY be biased as a GGG fan, but I'm going with losing at 160. hes young and still learning, and as he said himself "losses aren't as bad as people make it"..
Losing to GGG at 160, definitely. I wouldn't give him credit or respect for fighting and beating a drained GGG for the middleweight titles at caneloweight.
This sums it up perfectly and applies to most things in life as well!
Winning is all that matters.
with respect to both your opinions, i disagree.
trying despite risk of failing is the real victory to me.
