Elie, 23, was a second-round pick by the Stars in 2013. He scored six goals and 14 points in 72 games with Dallas last season, his first full campaign in the NHL. Two of those goals came against the Sabres.
Defenseman Jake McCabe said Elie left an impression as an opponent in those games, too.
"Yeah, I mean he's a big body," McCabe said. "He protects the puck well, he can skate well, he's got a good shot. When you combine all those things, he's a dangerous player there down low, for sure."
The Sabres have asked Elie - listed at 6-foot-1, 215 pounds - to bring a power-forward presence to their lineup. Housley has praised his physicality and ability to win battles on the forecheck.
"They just want me to play my game," Elie said. "Be a power forward, get on the forecheck, use my speed to my advantage and just play the game the right way."
That's not to say he can't contribute offensively, too. Housley went back and watched video of Elie from last season and came away impressed with the forward's playmaking ability.
"I like the way he gets on the forecheck," he said. "He's a big body, he can finish checks. When I see him play, I think he can make plays. He knows what he's going to do with the puck before he gets it, he's got a terrific shot. So, he'll get an opportunity at some point."
