He has already benched Shattenkirk and center Kevin Hayes for long stretches in games and made forward Vladislav Namestnikov a healthy scratch for New York's 3-1 loss at the Buffalo Sabres on Saturday.
In addition, Quinn doesn't hesitate to stop drills in practice if he doesn't like what he's seeing. He did it Wednesday, when the Rangers were working on the power play but passing the puck around the perimeter, passing up opportunities to find shooting lanes. Quinn got in the middle of zone and loudly said, "Shoot the [darn] thing. This isn't a beauty contest. Get pucks to the net."
"No one is really safe," said Hayes, who was benched for 11:25 straight in the second period and the final 6:49 of the third in Buffalo on Saturday. "Everyone has to play well to get their ice time here. It's a fresh face and he has his way of doing things. I think what he does is great. He doesn't let guys have days off."
"Really, it's more wanting to see me compete more, just be a little harder to play against," Shattenkirk said. "I know it's a very vague term, but when it comes down to it I could probably just be harder on my one-on-ones, lean into guys a little bit more, be a bit meaner. I know I'm not an overly physical guy, but I can definitely play with a mean streak. I need to get that back in my game because it does drive me."
Quinn, though, is respectful of the tightrope he's walking between holding his players accountable and having veterans turn on him for going too far. That's why he insists on having open lines of communication between coaches and players.

Hayes and Shattenkirk said they initially didn't know why they were being benched in the games last weekend. But following the games they each had separate meetings with Quinn, with assistant Lindy Ruff in on the meeting with Shattenkirk.

Their voices were heard. There were no blurry lines after those meetings, each said.

"When you do stuff like that there's got to be clarity and there's got to be explanations," Quinn said. "At the end of the day, accountability and performance are what this is all about. That's coaching, in my opinion, holding people accountable but also understanding people have built up a bank account too. You don't just bench guys for every mistake, but to me the piece to it that is non-negotiable is effort. If the mistakes are made because of the lack of all-out effort then I don't care what your bank account is, you'll be held accountable."
