Lalonde said that not only is Seider relied on in crucial situations, the 21-year-old is also thriving in various roles in which the Red Wings coaching staff have placed him.
"I don't think people appreciate how much we ask of him," Lalonde said. "(He's on the) first power play (unit), first penalty kill, every tough matchup and the minutes he plays. Right now, he's just passing every test."
It's a lot of responsibility, but Seider isn't backing down from the challenge.
"That's what you dream about," said Seider, who won the Calder Memorial Trophy as the league's top rookie last season. "You always want to be out there against the best lines and do your best to shut them down."
Through 55 games this season, Seider has 30 points on four goals and 26 assists.
"Early on, there were some ups and downs in his game," Lalonde said. "But I think he's overweighing some of those downs."
Seider said he is focused on developing as a player whose contributions go beyond the scoresheet.
"I think I'm more of a funny guy who always has a smile on his face," Seider said. "And hopefully can contribute that way to making the team better. Sometimes it's just small talk - helping guys feel good before going on the ice. If I can do that too, I'm really happy with my role on the team. For us, it's more leading by example on the ice. The better I can play, the better statements I can set in the locker room too."
Ben Chiarot said he's impressed by the way Seider plays and carries himself.
"He's a great player and he's gonna continue to get better as he gets older," Chiarot said on Feb. 13. "Easy guy to play with. Obviously really talented, so just give him the puck and let him do his thing."
