Though some of those players have been enjoying retirement for years, Carcillo, Burish and Eager are working out their post-playing plans. They're not quite as comfortable with their alumni status. They're still determining a way forward, just as they figured out how to play as 30-something member of the alumni team.
"Obviously the transition after retiring is tough, so to see St. Louis's alumni and Chicago's alumni, how strong they are, how tight of a community they are, to be able to tap into that as a 31-year-old leaving the game I think is very important," Carcillo said.
"Just really encouraging, just a whole lot of fun to be back in the locker room, around like-minded people, comfortable, just having fun and playing hockey and doing what we know."
For Carcillo and Eager, part of their transition has been done together, in Chicago, where they own Jet Hockey Training Arena in Glenview, Illinois, and where they're coaching an AAA youth hockey team.
They are also working with Carcillo's Chapter 5 Foundation, which aims to help players with the steps following their NHL career.
"It's just different when you go from doing the same thing for your whole life and all of a sudden it's over," Eager said. "You're at home, and if you don't get into something or at least have a plan, it turns into a long summer."
But the two have managed to stay busy, even when they're not on the ice.
"We're around each other a lot. We have a little mini-dressing room feel that we go to most days," Eager said. "There's a lot of guys in the Chicago area, so we're trying to let them know that we can still get together, hang out. Hockey players like to hang out with hockey players."
But even as those most recently in the NHL are working on what comes next, they were more than glad to slip back into their old uniforms, to get back on the ice, to return to the game, to hang out with hockey players as hockey players again, even if it was just for one afternoon in an exhibition game at a baseball stadium.
"You're probably never going to get the same feeling as playing in front of 20,000 people, but there's still a lot of similar feelings you can get," Eager said.
