Stopping the Maple Leafs begins with slowing down their youth. Toronto's top three scorers are all rookies: Auston Matthews sits at the top with 60 points, then comes Mitch Marner with 57 points and William Nylander with 56. Those three also rank second, third and fourth in scoring among NHL rookies, while defenseman Nikita Zaitsev (33 points) and forward Connor Brown (31) rank 11th and 12th.
Those skilled rookies help comprise Toronto's power play, which sits atop the League at 24.1 percent.
"I think going against a team like Toronto, the best way to kill a penalty is not to take too many penalties," Sabres defenseman Zach Bogosian said. "Stay out of the box and not give them a chance to carry that momentum whether they score or not."
Buffalo's power play has been almost just as effective, sitting right behind Toronto at 23.9 percent. It will have a different look, however, with Ristolainen out. Dan Bylsma has elected to use five forwards on his top unit: Ryan O'Reilly, Jack Eichel, Evander Kane, Sam Reinhart and Okposo.
Bylsma said he's used the five-forward look before, and its O'Reilly's ability to man the point and assume the defensive responsibilities up top that makes it possible in this scenario.
"When you do it, you're putting your best five players on the ice in an offensive situation," Bylsma said. "You need to have a special guy on top to be able to do it, a guy who's comfortable there, responsible there. You're flipping the switch a little bit when you're standing back on the point as a skill guy versus being a defenseman standing there. For some players it's a little bit of an island, it's a new experience and a little bit of an island, but Ryan's been there."
