Sure, and that same bottom 10-12 roster had a (vegas odds) preseason prediction of 85 points this year.
According to Vegas they were the 10th ranked team in the west with +250 odds to make the playoffs pre-season.
He has smashed expectations, he will bring them probably to +15 points above what was expected and comfortably secured them a playoff spot with Tommy Novak, Luke Evangalista and Colton Sissons as their 2nd liners... Those guys have NEVER surpassed 40 points in their lives before this season.
The job he has done is nothing short of remarkable and discrediting him is absurd. And since you bring up the Flyers and Torts, they had a pre-season expected point total of 76.5. The Flyers are currently 7 points above what was expected - The Preds are already 9 points above what was expected so yes he is actually doing an even better then expected job then Torts is with the Preds
The only team with a higher points tally above what was expected is Vancouver and Dallas lol. Edit- and Washington sorry
