I love how the concept of offense AND defense both being capable of thriving is anathema to HockeyGuys. If you cannot get elite numbers out of an elite offensive player that is a major f***ing problem, even if you manage to overachieve in some ways. It also conveniently ignores how drastically scoring has gone up these last few years. Getting 65 point paces out of Barzal is a cry for help.
The Islanders were a one-way 35-37-10 team the year before Trotz got there (undeniably bad, 29th in xGF%), and they were a 37-35-10 in his last year, which doesn't count. Guys like Pulock and Pelech were in their first full seasons too in 2017-18; their goalies were upgraded massively in that timespan. Over Trotz' years the Isles finished 16th, 20th, 11th, 22nd in xGF%. While acknowledging Trotz is still on the above-average end of the spectrum, it's amazing how the narrative around him has changed in 5 years.
