Some of that experience came from coaching Switzerland's national team at the 2006 Turin Olympics, a team that included current Team Europe defenseman Mark Streit and one that defeated Canada 2-0 in group play, an upset that would at least be comparable to Team Europe taking down Team Canada in the best-of-3 World Cup final, which begins Tuesday (8 p.m. ET; ESPN, CBC, TVA Sports).
Krueger's knowledge earned him a chance to go through the Olympic process with Babcock, participating in meetings starting at the 2013 NHL Draft on June 30, 2013, right up through the Sochi Games in February of 2014.
Krueger said he only knew Babcock "peripherally" before he began working with him, but that quickly changed at the Olympics.
"After that it was really intense actually," he said. "We would run together. We would speak about hockey nonstop together, and it was the best coaching clinic I could go through with Claude Julien, Ken Hitchcock, Lindy Ruff and Mike Babcock. From the draft in [Newark] right through the Olympic Games, I was with them.
"The only thing that was sad about it was I didn't know where I was going to use it because I was in football, and so that learning process with Mike and his staff is really a lot of what I brought into Team Europe."
Now Krueger is going to use what he learned in an attempt to defeat his mentor, as daunting a challenge as that might be, and Babcock is clearly not going to take his former protégé lightly.
"[Team Europe] got better every day, Ralph and his staff have done a good job, the players have done a good job, they play well without the puck and the goaltending played real good [Sunday]," Babcock said. "I think they're a real good team and obviously we're going to have a test. They've earned the right to be here by doing things right. They're no different than us."
That is true in more ways than Babcock probably knows.
Krueger's team has evolved from one that began its pretournament schedule without an identity into one that can smother opponents with its structure.
