Beterbiev doesn't punch from the defensive posture, and Gvozdyk is far to quick offensively for Beterbiev to ever get his offense going. I'd take Gvozdyk 9/10 X. And by KTFO each time. Gvozdyk KO4-5 Beterbiev.
Jacobs PROVED the Mora KD to be a fluke, the Pirog TKO to be due to inexperience due to being KD'd big for the first time in his pro career, while up big on the cards, and showed flashes of brilliance both off the back foot, and from the SP stance in stifling GGGs forward momentum when he was clipped hard. Jacobs chin is no LESS than serviceable, if not solid. Same for Ward, whom I despise. Ward's chin might be described as iron.....not granite, but no less than solid, and far greater than serviceable.
