Sure. Just like he took those right hands from Boone, Ward and Alvarez like light refreshments too right?
Nah, different puncher, but for weight and raw power Beterbiev is quite obviously a heavier puncher. Better delivery yes goes to Kov, but as for proven, its just opinions !
Their power is just different. Kovalev's power is at the end of his straight punches. And Beterbiev's power is in his hooks. But if we forget that they are boxers and want to look at them as just, well, two persons (or, let's say athletes) Beterbiev is stronger.
