One thing Ristolainen is not struggling with anymore is his English, which has improved dramatically since he made his debut as a first-round pick with Buffalo in 2013. Also improving has been his play this season. The big contract hasn't caused any undue pressure on him.

Ristolainen played 23 minutes, 17 seconds in the season opener against Montreal, 26:43 in Sunday's win in Edmonton and 26:04 in Tuesday's overtime loss in Calgary. Coach Dan Bylsma said over the summer he was hoping to cut back on some of Ristolainen's minutes this season. Bylsma laughed when reminded about that Wednesday and admitted it's been no dice in that area so far.

"I played a lot last year and I certainly don't want to play less," Ristolainen said. "I want to be better. I'm in better shape and I think I can handle as many minutes as I earn."

Ristolainen had three assists in the game in Edmonton and has been a key part of the Buffalo power play, which entered Thursday's game 4 for 16 and seventh in the NHL at 25 percent even with the loss of Jack Eichel and Evander Kane to longterm injuries.

"Our PP has been OK so far," he said. "We've had some goals and we've got a great unit going. We're not going to be satisfied. We have to work on it every day and we can get better."
