Nico Hischier might only be 18 years old, but he’s already revealing a maturity that’s well beyond his years.

New Jersey Devils general manager Ray Shero told The Star-Ledger this past week that the forward asked head coach John Hynes to “just (bleeping) bench me,” after the No. 1 pick in the 2017 NHL Draft took a penalty 45 seconds into a 3-2 overtime loss to the Edmonton Oilers on Nov. 9.

Two nights earlier, in a 3-1 loss to the St. Louis Blues, Hischier took a penalty 36 seconds into the first period.

The Devils were shorthanded 44 times and were in the lower third of the league in terms of penalty kill percentage (79.6) in the month of October.

Something had to change.

“We had talked to the team about controlling (penalties) and if it didn’t get better, guys were going to sit for a certain amount of time,” Hynes said on Saturday. “We held strong to that and made it clear that it didn’t matter who it was.

“(Hischier) took a penalty the game before. We addressed in between games. He took the first penalty in the next (game) and he came back down and I said, ‘You’re going to have to sit for a bit,’ and he said, ‘I should. It’s my fault.’”

Hischier sat for just over seven minutes but still managed 21:18 of ice-time in the game. He hasn’t taken a penalty in three games since his brief foray riding the pine.
