Name me any good/great players who couldn't skate?
Derek Stepan's skating makes me nauseous.
I believe the point he's trying to make is that being an above average nhl skater is not, in and of itself, enough to make one a good nhl player.
Id imagine that for every talented, smart hockey player that couldn't skate well enough to make it there's two or three great skaters that didn't make it because if what was (or wasn't) between their ears.
