Ah shadup. Many fighters, even those with a bunch of KO losses, never reacted or looked quite like that in the ring. I don't think Bruno was purely chinny as he did manage to fight through some horrible moments, but there was definitely something off with the way he reacted to big punches. It would have been less suspect if he'd been clean knocked out a few times, rather than as said look like he'd literally been electrocuted a bunch of times, even if he came through to win one or two of em.
