i cant say for sure obviously since i am not Pascal, but i could tell from the second round that he would tire badly due to his movement and how tight he was. a couple of times after the bell, he seemed like he had held his breath the entire round.i have seen it before, and i knew Pascal was winning the fight on points, i just hoped he would have enough to make it to the last bell. great win for pascal.
After round 8 he seems exhausted meanwhile Dawson start to gassing, is this a tactic or he just simply tired?
Pascal have great stamina and he proved it many times before, Dawson thought he was going to be one of the GOAT "he said that in Montreal", but in the ring with the faster Pascal he was in trouble. Dawson in the later rounds new that he had to KO Pascal to win cause he was already losing the fight badly. So he went after Pascal in panic of losing is "0" but it didn't work. Pascal was never in trouble in that fight, the 11 round was Dawson trying to impress some judges with fast but low power shots. Pascal will win the rematch by KO.
I think he was more worn out mentally than physically. He didn't know what to do with Pascal and just seemed like he didn't show up to fight that night.
