Power, the No. 1 pick in the 2021 NHL Draft, was plus-2 in 19:28 of ice time. He signed a three-year, entry level contract with the Sabres on Friday after completing his sophomore season with the University of Michigan, where he had 32 points (three goals, 29 assists) in 33 games.
"I think I was pretty calm but obviously there's going to be some nerves," Power said. "There were definitely some but not too bad.
"I think once you got the first one (shift) out of the way you kind of get into the rhythm. I think it kind of calmed my nerves down, and a nice showing like that is pretty easy."
Power grew up in Mississauga, Ontario, about a half-hour drive west of Scotiabank Arena, and was in the starting lineup.
"He was great, that's a tremendous job," Sabres coach Don Granato said. "As I've mentioned beforehand, there's no doubt he's rehearsed in his mind being in this building and this league many times, and it looked like it; it looked very from the drop of the puck. He had a little fun with his skate there, but he's a very balanced person, and I thought he was outstanding tonight.
