So, this is a style that I gained when I was a little younger. I used to coach hockey in my area, and the rule we had with our team was that on Home games, you have to wear a suit. And on away games, the whole team wears the team tracksuit and team logos and colors. It would be a good way for everyone to come in dressed the same and also, since it is an away game, it is a lot easier to travel in a tracksuit. The mantra of "Look good, feel good, play good" is super important when youre playing competitive sports so it is about trying to make sure you check off all 3 of those in that particular order. Plus, nowadays, trying to convince people to dress in suits all the time is going to discourage many people, that style is not like what it used to be. Its all about athleisure and comfortable clothes, maybe get the team some Lululemon sponsored outfits in team colors, that would make the guys come to the rink comfortable and super ready for the game in my opinion
