A lot but also Eubank is old and unmotivated. I wouldn’t be shocked if Benn beat a non rehydration cause Eubank at 168 even. He has no shot against Eubank when Eubank was his age though.
I think they both played a part, but I'd lean towards age/mental fortitude as being the main reason. Usually, with the rehydration clauses, you see a strong 3-4 rounds then a rapid fade. Eubank just didn't look good from the beginning.
A lot, but that sword cuts both ways. Don’t you think Conor Benn is affected by fighting someone way bigger than him? This is why we have weight classes, and if you want to try to fit a square peg into a round hole like this then that comes with advantages and disadvantages to both fighters. But people want to take up sides and only play up the negatives for their side and build a narrative that way.
I think a lot, without taking anything away from Benn, who had a good match, certainly tactically better than in April. Eubank looked like a ghost, probably the weight clause affected his performance a lot.
