"It was really surprising to me, and everyone in Germany was so happy and excited for me," Seider said at Detroit's development camp in June. "But now I'm here, and I don't have to look back at that. I can look forward at the rest of my career. It's going to be fun."
Seider (6-foot-4, 183 pounds) was the second defenseman selected behind Bowen Byram, who went No. 4 to the Colorado Avalanche.
"We think he has excellent hockey sense, obviously a big kid, 6-foot-[4], real good skater," said Steve Yzerman, who replaced Ken Holland as Detroit's general manager April 19.
Seider is the first Germany-born defenseman to be selected in the first round of an NHL Draft. He played in Germany's top professional league, where he faced older, more seasoned competition, and had six points (two goals, four assists) in 29 games for Mannheim.
