And on the flipside of that, going for the puck there means you can miss and you actually get burned on the play. Hell, even an effective pokecheck just dislodges the puck...which means another loose puck battle for which Carrier to board Doughty in. No, every level of hockey will teach you to play the body there. Doughty didn't play it perfectly, and here we are, but there is no d-man worth his salt that goes for the puck only there.
Hell, even high-level roller hockey is 'non checking' and they'll tell you to play the body there too.
