Seider (6-foot-3.5, 183 pounds) missed three games of the World Championship because of an injury sustained in the round robin but had two goals in five games and averaged 13:47 of ice time per game — fifth-best among defensemen for Germany — in the tournament.

He impressed in his brief showing.

“He plays like a 35-year-old, almost,” said Draisaitl, teammates with Seider at the World Championship. “He’s so calm and so collected. It’s pretty fun to watch. Hopefully he keeps developing the way that we think he will and you know he’s going to be a special player.

“It’s great to have a young kid coming up that seems to have the potential to be very, very good at hockey.” – Aaron Vickers, NHL.com

“In my eyes, he is the best German defenceman to come along in ages,” Thomas Roost said, a Swiss-based scout with the NHL’s European Scouting Services.

“He already plays like a veteran most of the time. He plays a mature game. He carries a very strong stick and wins a lot of battles in the corners, in the slot area and along the walls because of his strong body and especially because of his strong arms. I really like his mobility and his high-percentage plays. What is also an exceptional asset are his successful zone exits. He moves the puck very well or skates with the puck and his zone exits are successful with a higher-percentage than the average (defenceman).” – Sunaya Sapurji, The Athletic 

It is extremely rare to see a highly-touted draft-eligible player coming out of the DEL, but Seider is all that and more. The right-shot defender witnessed his stock steadily rise throughout the course of the season, and begin to skyrocket in the back half. This was due to his increased role on the Championship winning, Adler Manheim squad. His five assists in 14 playoff games may not jump off of the page, but his impact was felt in all situations. He was also named the league’s rookie of the year.

Seider completed his year on another high note, becoming one of the youngest defensemen to score a goal at the World Championships. He produced two goals in five games while seeing second-pairing deployment. The 17-year-old blends impressive physical tools with high processing speed and decision-making. This leads to consistent and accurate reads on both ends of the rink. His upside is tantalizing. – Cam Robinson, Dobber Prospects
