Agreed. The exceptional skating d man is a hot commodity in today's game. Also make sure his coaches teach him to play the game the right way both in his own zone and offensively. Let him take risks rushing the puck if the other team gives him ice. High off the glass isn't the way to go.
Good luck finding Daddy Coaches that understand the game and are going to let your kid develop his offense from the blue line. Most don't even teach stick on puck. Even the ones that played low level pro think the game is still the way they played it back in the 80's, or whenever it was.
Best thing to do is to go out and find a coach that understands today's game, and stick with him.
