The crux of Kudryashov - His boxing routines in the ring is literally only to set up the big power punches - and the 'routines' he uses all involve power shots rather than doing anything to attempt to outbox his opponent.
he already has much better wins then oganov ever did. he only ever beat two guys with half decent records. once dirrel beat him, he lost to prospects with around ten pro fights.
He does have crazy power, but I think we need to see him do it to a better level of opponent before we start mentioning him with the likes the Jackson.
Jackson could box a bit better, though his power was certainly of the world ending variety. Shavers might be a more appropriate stylistic comparison in terms of just how important power would be to his game.
