Like you, during the week of the “Y-oh-why-do-we-keep-playing-these-bozos” game the only blue I wear are my jeans. I’ll wear red every day that week.
I always wear Utah gear the day before and the day of a Utah game.
I have one Utah shirt I wear during each game and only wash it after a loss. That shirt may be different from one season to the next, but will be the same for the whole season.
All year long, if I’m eating M&Ms, I eat the blue ones first and the red ones last (Utah is the last team standing). I eat the orange ones just before red, in honor of my brother who passed away (orange was his favorite color).
