Oh man... that's a rough one, iceg.
I'm not a sports fan myself, but I can relate to certain times of the year being triggers. For me, it is all of the major holidays, starting with Halloween. I've got majorly painful stories that coincide with each of those dates, but I'll use Halloween as an example.
A month prior to d-day, I was trying to carve pumpkins with my son. I wanted my wife to participate. She blew up at me, and went upstairs. I ended up doing all of the pumpkin carving after a verbal beat down. Little did I know, she was upstairs planning a rendezvous at our house the very next day with OM while I was at work. I didn't find this out until I discovered the emails almost a month later.
Fast forward a year, and man was Halloween going to be a trigger. We ended up taking the path of reclaiming the day, and going out of our way to make it special. Not only did we carve pumpkins, but we took the entire family an hour out of town to go to a pumpkin patch in the country to pick our own pumpkins out. After that, we carved the jack-o-lanterns, roasted pumpkin seeds, and had a good time. We kind of reclaimed the day.
I'm wondering if you could do something similar, and make the onset of college football season a huge deal. Get some Gamecocks paraphernalia. Deck your wife out in a Gamecocks jersey and hat. You have every right to cheer on your Gamecocks, and you deserve to not have to trigger about it.
Just a suggestion based upon my experience.
Best of luck to you. Hoping you are able to get through this upcoming season with minimal triggers.
