Yes his shot is better from what I can see. He doesn't get it away as much, but it does have the zip back.
About the PP, they need to utilize the point man more. I know Salo is not here, but they need to use them to spread the pp. When the 2nd unit comes out, Nazzy is the only threat when he's on the half boards, so the other teams will rush him. If you can move the puck around fast and use the point man, Nazzy will see more room.
