Seney understands he needs to continue to play a hard and responsible game to remain a fixture in the lineup.
"It's definitely in the back of your head, earning your role and sticking on the roster," he said. "I think every day is a new opportunity to go out there and show what you could do and kind of move up that ladder. Being a smaller guy, maybe I have to take a couple more strides out there to keep up with some of the bigger guys with longer strides.
"I think for as long as I can remember, skating has always been my best asset and that was something from a young age that I knew, as a smaller guy, if I wanted to make it, I had to skate so that was a huge focus. I proved to myself I could play with these guys and getting it done in college was probably the point where I kind of had that thought that making it to the NHL was a possibility."
Seney, born in London, Ontario, dreamed of playing in the Ontario Hockey League, but instead felt the Ontario Junior Hockey League and college route would be a better fit.
He wasn't surprised to be passed over his first year of eligibility in the 2014 NHL Draft as a second-year player in the OJHL with Kingston.
"I put up a lot of points (69), but I think there were a lot of parts to my game that I needed to improve too," Seney said.
Seney began opening some eyes as a freshman at Merrimack College in North Andover, Massachusetts, in 2014-15. He scored 26 points (11 goals, 15 assists) in 34 games and was drafted by the Devils.
Seney played four seasons at Merrimack and scored 115 points (42 goals, 73 assists) in 139 games before the Devils signed him to a two-year, entry-level contract March 16. He had 18 points (four goals, 14 assists) with Binghamton of the American Hockey League in 22 games the past two seasons before being promoted.
"I was quite a bit smaller when I was 16, so I started looking at some school routes (including University of Massachusetts, Clarkson, Providence), and watched college games and fell in love with the atmosphere," Seney said. "Merrimack was a smaller school, a lesser-known school, but the staff there with head coach Mark Dennehy and assistants Curtis Carr and Bill Gilligan really helped me a lot."
Dennehy was hired to coach Binghamton on Aug. 1, so he knew of Seney's skating ability and opportunistic mindset in the offensive zone.
"What I'm proudest of with Brett is, No. 1, he's an unbelievable competitor," Dennehy said. "He plays his tail off, he wants to play fast. He's incredibly dynamic, and he really worked on getting stronger."
