With the upcoming inaugural game coming up. I'm considering what traditions will pop up.

Around the league, it has become tradition to emphasize words in the National Anthem. For example, in Dallas everyone yells "Stars" at the given spot, since they are the Stars. In Calgary they emphasize "see" and "red" for their "C of Red" slogan.
At UHC games, I wouldn't be surprised if the "you" starts to get emphasized. If they adopt the Yeti mascot, they might start emphasizing the "yet". There are several slogans that they could incorporate with "yet".

Speaking of U. It would be a travesty if the diminutive "U" hand gesture gets adopted for the team. I know some people have used that. BYU fans would never embrace it, though.

They need to go with a sizable U, I would hope that something like the touchdown signal is adopted for the U. This is the big leagues after all.
