Who ? Why ?

I have not put Usyk on this list, because he moved up recently (he has been almost unbeatable at CW, definitely).

Canelo's case is a little bit different, he might be back at MW, again...........

Inoue by a hair over Crawford. Terrence won't be fighting anybody with a chance anytime soon, but there are guys in his division. I'd pick tank over loma.

There is no unbeatable boxer. Anyone, on the right day, can be beaten including Marciano and Floyd.
All of the top four Heavyweights will have a loss by the end of 2021.

Nobody's unbeatable, but Inoue certainly looks to be a force in his weight range for a long while to come.

...I stopped placing that much value on the perfect immaculate records as well as the seeming "unbeatability" of the boxers...Generally speaking I believe the road warriors belong to the endangered species and are a lot more vulnerable compared to the home town legends..

Tank Davis

Inoue, just destroys top level opponents

Lol at Briedis, Ruiz, Wilder, Fury. They're beatable, most of them even have already lost.

My vote goes to Inoue.

Inoue right now in my book!!

Inoue by far
He knocks out top level opponents in 3 rounds.
Donaire won't pass 3 rounds

How the hell is Briedis on this poll? This dude got beat.

Inoue followed by Loma. Loma would be first but he's fighting probably two weight divisions higher than he naturally would.

Usyk, Inoue, Loma, Crawford, Tyson Fury.
