Broner in 2014. Wilder in 2018 when he finally fights someone under 40 and with a record better than 16-26 Ward in 2014 when he gets KTFO by Saint George Groves.
Why even bring this up? You should want to hide this fact if the politically, socially and economically superior european man adjudges you to be at the bottom of the social hierarchy. My answer: Fury (But I'll throw Broner in too)
If I had to guess probably some of these British fighters as soon as they step up from Domestic fights. We see it time and time again.
Tyson, Broner and Wilder will all get clipped eventually. I have a feeling Broner takes the best punch out of the three, lb for lb.
Adamek, Harrison, & Judah don't belong on the list. Adamek is getting up in age and is a small HW. The other 2 have already been "exposed", AH many times. Of the remaining fighters I'd say Wilder, if he ever fights a few live HWs.
