Less than 24 hours later, Stastny and his Blues teammates were at Busch Stadium on Saturday to watch the 2017 Winter Classic Alumni Game, featuring Paul's father, Peter Stastny, who scored a goal in the 8-7 win for the Blues alumni.
"It was fun. It was just something he's done 450 times in his career," Paul Stastny said about watching his father score. "I knew if he wasn't going to get a goal or an assist, I think he wouldn't hear the end of it from my mom and my sister, and me and my brother, for sure, down the road."
The Blues did not look anything like the group that was so angry at themselves the night before. They were smiling and laughing and taking it all in, somewhat awestruck by the legendary players walking around the St. Louis Cardinals clubhouse, which was used by the Blues alumni.
The Blues (19-13-5) probably need some fun right now, and that will continue Sunday when they and the Blackhawks will practice for the first time on the ice at Busch Stadium to prepare for the game Monday (1 p.m. ET; NBC, SN, TVA Sports, NHL.TV) and get to spend some time with their families and loved ones on the ice during family skating sessions.
The Winter Classic is serving a valuable purpose for the Blues near the midpoint of the NHL regular season.
"This is very unique. I don't think this happens a lot in a lot of people's careers, especially when you're hosting the Winter Classic," Stastny said. "Everybody's got a lot of family and friends. I think this is one of those opportunities where, obviously the game's the most important thing, but at the same time, it's a whole event and you want to embrace it and have fun with it."
The Blackhawks could use a mental break just as badly as the Blues.
Their 3-2 loss at the Carolina Hurricanes on Friday was their fourth in five games, making it the worst stretch for Chicago (23-11-5) in what has been a highly successful season.
