Roy at 168 and 175 pre Tarver, was something special, Bivol is very good but i think Roy would be too fast and probably too good for Bivol. It would be sonething Bivol has never seen before in the pro ranks.
50/50 Yeah, im going there Bivol is one of the best fighters I've ever seen. Unprecedented intelligence. Supreme mobility. A demi god. A fight with RJJ is a tossup, but since Roy has the resume I'll vote him for now
It's been shown repeatedly that fast, slick fighters are Kryptonite for robotic, Soviet fighters. Roy by 12-0 shutout.
Bivol is a good light heavyweight, possibly great but Jones Jr was on a different planet of ability in his prime. Roy would land one off shots at angles with enough power and pick Bivol apart with his hand speed. Roy wins this easy.
