A 200lb body - even on a missed hit - hits exponentially harder. From a hockey perspective, Skinner's hits/60 is meaningless. He doesn't skate fast enough, or weigh enough, to draw attention unless he has the puck. When Kane is on the ice, the opposition is hyper aware at all times, so hits/60 is not a valuable measurement of hockey. One Kane hit is worth more, in the period, the game, the series.
Skinner can create space and score goals - the hardest things to do - but he's not hard to play against. When Deboer was asked why the Oilers dominated, he said we were harder to play against than last year.
