while I agree with your first paragraph, this is not in fact what TC did, this was not a team of players who had a shut down line, had an energy line then had two lines relied on producing most of the offence. This was a super soft TC team as far as players whose natural instinct is to play with any physicality
When the team was announced, the only players I knew much about were a few WHL players so I couldn`t really comment on what or how I felt about the team but having watched them now, it appears to me the approach was to try to stack the lineup with guys who score, problem is, most of these guys do it for their respective teams and are looked at as THE man, only one puck to go around
Again, even after watching their first game vs Finland, I recognized many worrisome issues, the biggest, zero identity, I couldn`t pinpoint one line that as a coach, you could tap on the shoulder and go make life miserable for the other team as far as energy, physicality.
Quick look at say the 2013 squad, Camara, Danault, Rattie brought that energy, 2017, Nick Roy, Blake Speers brought that energy, even in a losing cause in 2003 in Halifax, Tootoo, Scottie Upshall, our old friend Soupy was on that team, the emphasis was not solely on scoring it was truly on a balanced roster, now, they didn`t win it all but at least they had an identity, this team was creampuff city from game 1
