Whenever a team is struggling, there are frustrations that just have to come out sometimes in order for the struggles to end.  

For the St. Louis Blues, those frustrations came out in the form of a fight at practice between teammates Robert Bortuzzo and Zach Sanford during the season when the Blues were struggling.

Everyone knows what happened after that fight.  St. Louis went from last place to winning their first Stanley Cup ever and fittingly, Bortuzzo and Sanford hugged one another as soon as their captain lifted the Stanley Cup.
Everyone else was watching Alex Pietrangelo life the Cup except for the two that fought in practice and that might be our favourite moment from the Blues' celebration on the ice that night, aside from the moments the players spent with superfan Laila Anderson.
