Their shooting percentage has been poor, close to 8% over the past several years. But I'm saying I think this is due to lack of scoring talent rather than any systemic thing implemented by their coaching staff.
Consider Bill Peters who suffered from having the 2nd lowest shooting percentage team in the NHL during his tenure in Carolina from 2014-2018 (behind only Buffalo, another team that has lacked scoring talent in recent memory). But last year Peters coached the Flames to the 3rd highest shooting percentage in the league behind only Washington and Tampa Bay while also being a top 5 shot-share team. Doesn't this suggest that maybe the problem in Carolina isn't with their system but with their lack of high-end scoring talent over the years?
With players like Aho, Svechnikov, Teravainen, and Niederreiter up front now they have a much more talented forward corps than they have had in the past. They still aren't nearly as talented as the top-end players from Washington, Pittsburgh, or Tampa Bay but I'd be surprised if they are in the basement of the NHL in terms of shooting percentage again. Because of their upgrade in forward talent and the indication that they will once again be a dominant puck-possession team I really think they can compete for the division, as long as they don't have poor goaltending as they had in the Peters years.
