Hayden flashed his skill set during Buffalo's preseason opener in Columbus, when he won a battle along the boards and set up a goal for Arttu Ruotsalainen in the crease.
It was the sort of play coach Don Granato came to expect from Hayden during their shared time together, first with the U.S. National Team Development Program and later with the Chicago Blackhawks.
"He's an up-and-down, throwback-type player," Granato said. "Just a straight-line, hard-nosed guy. But he has a presence. Guys enjoying playing with him, on a line with him. He makes room for his linemates, teammates, and he takes a lot of pride in that."
The Sabres enter their final preseason game with 16 active forwards on the roster (including JJ Peterka, who is day to day with a lower-body bruise but skating on his own). That number will be trimmed to 13 or 14 in time for the regular-season opener next Thursday.
Hayden, a third-round draft pick by Chicago in 2013, seeks to make Buffalo his fourth NHL team in as many years. He left Chicago for New Jersey in 2019-20, then played 29 games for Arizona last season.
For as many cities as he's explored, he's maintained a consistent role in the NHL. His last AHL game came during the 2017-18 season. He has 24 career games in the AHL and 185 in the NHL.
"It's on me to show up every day and put my best product forward and give myself the best chance to be here as long as possible and stick around and help the team," Hayden said. "It really is just a day at a time mentality."
Here are more notes from practice on Friday.
