The Sabres spent a large portion of their practice on Monday working on special teams, and the four remaining members of that unit were back together. The one change: Jeff Skinner - with 98 power-play points under his belt in eight seasons - has taken the spot formerly occupied by O'Reilly.
Housley emphasized that the units can change between now and Thursday - the Sabres practiced with Patrik Berglund, Vladimir Sobotka, Conor Sheary, Casey Mittelstadt and Rasmus Dahlin on their second unit on Monday - but Skinner said he's already picked up on the chemistry between Eichel, Reinhart, Okposo and Ristolainen.
"Coming in as a new guy, you just sort of read off them," Skinner said. "Obviously, they've got some chemistry, they know where each other are going to be on the ice. For me, I just try and slide in and sort of be in the right spots for them, and when I have the puck know where they like to be and where they like to have the puck."
Okposo has said in the past that the unit's success is largely based on their like mindedness - they all think the game well and they all think it similarly. Skinner said he's picked up on that, but he's also come away impressed with their work ethic.
"I think that helps a lot, but also I think the compete and the battle level is just as important," Skinner said. "I think all four of those guys win a lot of battles. When you're on the power play you need to have the puck and winning the battle is sort of the start of that.
"I think that they've done a good job of that lately from what I've seen. And then once you have the puck, I think their skill and hockey sense kind of takes over."
That work ethic, Eichel said, could be a key to making this campaign more like the second half of last season and less like the first.
"We've got to outwork," he said. "I think at times last year we probably got outworked on the power play and you can never have that happen and think you're going to be successful. It's a new opportunity for us."
