Let the players have fun. They work very, very hard and I like seeing them out there enjoying themselves. Maybe it looks a little dopey or seems over the top but why should I care? It's a GAME, not sacrament meeting. I see no evidence at all that it's distracting from anything, and I certainly don't think it's a meaningful difference between us and the elite programs.
Honestly focusing on this reminds me of the types of chaperons I used to see at youth dances who freaked out whenever anybody seemed to be having fun.
