That's not how this works.
He doesn't get credit for the team improvement simply because he was the coach, as if he's a puppet master controlling the play of the players. He didn't put up any points or make any saves. If you want to point to specific direct actions he's made, then fine, but the teams placement isn't proof of coaching quality. Especially when we can easily point to mistake after mistake after mistake when it comes to the thing he has the most control over... the lineup and player usage.
This nonsense of "AV took them..." and "AV has them..." are just empty words. As an example, we wouldn't say "
Hakstol took the team from a lottery team to a playoff team" or "
Hakstol has them in the playoffs" back in 2017-2018, right? That was because of the players.
The real difference is that our roster this year is better than our roster last year, in large part because of the difference between using 70 different goalies and having a legit starter in Hart. Plus getting hot at the right time with that winning streak, because before that our record was close to our record with Hakstol in his most recent full year.
