How do Beterbiev or Bivol beat Ward if they lack punch power or boxing skills?

How do Artur Beterbiev and Dmitry Bivol stand a chance at beating the granite chinned Andre Ward when they lack the boxing skills to compete with him in a boxing match? Whilst also lacking the necessary punching power to hurt him, never mind KO him since Andre Ward is pretty much immune to getting knocked out by the feather fisted punchers in Beterbiev and Bivol who can't generate the punching power required to KO the body of Andre Ward who has immunity to getting knocked out by supposed Russian / Eastern European 'power punchers'? Enrico Koelling was walking through all of Beterbiev's punches like they were nothing whilst Felix Valera was walking through all of Bivol's punches like he had the punching power of a little sissy. Why is Ward getting criticized for not boxing against these inferior breed of boxers like Beterbiev and Bivol as if they even stand a 1% chance of winning? They are like little toys and babies for Ward who Ward will handle with the utmost ease.
