From Game 2 GDT:
Yes. In fact back when they used to practice more under Bednar, I would notice both their PP and 5v5 got noticeably better, after they had an extra day or so to have a good practice.
I think that also helped them in the 22 playoffs, and played a part in their incredible execution, after the longer breaks between series than other teams had.
That said, I also can understand why they may not, since Bednar's system, and some of the player's like Nate's explosive style, are incredibly taxing physically.
My guess is Bedsy's default is to want to practice as much as possible, so there's a reason why he doesn't. Nate is probably a big part of that again, but I would bet they've also leaned into sports science and health in recent years, to fix their injury problems. Which have been better the last couple years. Also about when Bedsy stopped practicing as much.
This is a great article on the imapct of this role with the Leafs if you can access it. There's ways around the paywall too if you're familiar with them.
Former director of sports science and performance Jeremy Bettle: "It’s absolutely why they have more injuries."
