They both have a pretty good chance against Ward. Ward was still class at 175, but he was by far more effective at 168.
It would be interesting to see ward try his dirty rough house tactics against beterbiev who is a harder man than kovalev
Yes, Beter is definitely mentally tougher than Kov. Though it's worth noting, prime Kov was a good deal quicker than Beter, and Kov's quickness was part of why Ward struggled so much in the first fight.
Another question is prime Kovalev vs Beter and Bivol. Imo, prime Kov beats the Hell outta Bivol. 2014 Kovalev vs the 2019 Beterbiev? Now that's an amazing fuckin matchup.
