It's not just shot volume for Carolina though. The expected goals have been very high, so it's not as if they are just lobbing pucks from the point. They are generating goal scoring opportunities.
Carolina's rosters have exceeded expectations a bit because they have been so sound defensively and played such a team game. Reminds me of Nashville when they were good. Solid D, lacked the scoring up front.
In Carolina you have Aho who since Rod took over has scored at .95 ppg and then you have Svechnikov who scored at .75.
Rod's a bit of Tocchet in not allowing the offensive players to play offence as long as it outweighs the defensive part of their games.
