The event, which was announced Thursday and has been spearheaded by Larkin, is to honor the late Jim Johannson and proceeds will benefit the Jim Johannson Legacy Fund of the USA Hockey Foundation and the Ellie Johannson College Fund.
"It is special. The idea started at worlds, right at the end," Larkin said. "Jim Johannson's brother, John, was there. We were talking with Pat Kelleher, the executive director of USA Hockey, and how great of an idea it would be. We had a lot of steam behind the idea, everyone was rallying around JJ at the world championships and I saw that and I thought it would be a great idea. I know it was released today. It's going to be a special night, a lot of superstars coming into town -- Auston Matthews, Charlie McAvoy, Jimmy Howard's going to play. We're still working on other guys. It's going to be a star-studded lineup so it's pretty cool they're all coming in to honor him and raise money for a great cause."
Larkin said he sat down with Kelleher and Scott Monaghan of the U.S. National Team Development Program in June and came up with the idea.
"Now it's going to be an awesome event," Larkin said. "I'm not taking all the credit but I definitely have had to get on the phone, my job has been to recruit players, which is ironic. I feel like JJ himself when he's calling guys for the world championships and calling everyone. You get every answer and you got to understand that it's summer and people have families going to school at that time, or guys have things going on. It's been interesting, talking to different guys but mostly great feedback from that."
In addition to the players already mentioned, some of the others confirmed are Detroit's Danny DeKeyser and Luke Glendening, Columbus' Zach Werenski, Minnesota's Ryan Suter and Zach Parise, Winnipeg's Connor Hellebuyck, Calgary's Matthew Tkachuk and Noah Hanifin.
Coaches for the game will be Red Wings coach Jeff Blashill, Wisconsin coach Tony Granato, New Jersey Devils coach John Hynes and New York Rangers coach David Quinn.
Larkin said there's a reason that Johannson meant so much to everyone associated with USA Hockey.
"He was a special guy," Larkin said. "Just his patience with everyone. I didn't realize how much he did for USA Hockey in terms of every national team from men's, women's, sled hockey. His hands were in every national team, picking the teams. He knew all the players - women's, men's, sled. He knew them personally. He knew their families. The world championships. I remember my first year and my parents came and I was still a college player. Just seeing what he did for them, transportation from the hotel to the rink, tickets and flights and everything. Just special how generous he was to everyone. He treated everyone the same whether you were a player or a younger brother to a player. It was special what he did for USA Hockey."
It was a special day for the youth campers, who may not have known that Larkin was going to be there, unlike at the Larkin Hockey School.
