I could see the bottom six being in the same ball park. Why is Lucic now magically going to start scoring more?
The bottom six doesn't score much because they kinda suck.
Nothing magic about it. When any player has such a low as Lucic's calender 2018, they're absolutely likely to do better regardless of team factors. Which is why Lucic had more than twice as many goals in 30 games in 2019 than he did in 70 games in the year 2018.
The fact of the matter is that EVERY player involved underperformed on career norms beyond Chiasson and Kassian, to such a degree that it is not only improbable that it would happen to all again in the same way, it's just borderline impossible. I would literally bet thousands on it.
