Nobody is talking about you - wear whatever you want, who cares. Once again, nobody care what fans do currently, that is your choice.
It's the players that represent the University, posing as "Sioux" hockey players, that actually work against a current core mission of the athletic department which is to try and implement the new nickname and branding.
They will gladly take the 20K/year scholarship but can't respect the university enough to show some support in their time of transition. That's the problem.
