Gvozdyk is inadvertently leading future Beterbiev opponents astray. When he said people overestimate his power... no, Oleksandr, the mother****er clearly hits like a truck. I think it's you who's underestimating your own chin. Just because you were able to take his shots for 10 rounds... doesn't mean anyone else could.
The nail dodged a lot of leather early in that fight and was winning imo. However, once AB started catching him it was a slippery slope. Gvozdyk may be able to compare AB's punching power with the pimp who he put in hospital. That dude hit very hard and starched a few guys with single shots.
Gvozdyk is actually a very smart choice for Canelo to spar in preparing for Bivol. Similar size, similar elusive style. Some might even rate Gvozdyk as better than Bivol, which would not be unreasonable.
