Wyoming has a D1 football team and a BFA in theater. I think the only way it could work is to do general courses in the fall and theater classes (and productions) in the spring. They do 3 major productions in the fall and 3 in the spring. There are some required theater classes that don’t require practices that could be done in the fall like history of theater, costuming, make up, but to be in a production wouldn’t work with football. This may require an extra semester or year academically after his football days are over. Wyo doesn’t have a BA in theater, but does offer a minor.
Montana also has theater and D1 football. Idaho.
A friend had two children at Coastal Carolina, one in theater, neither in football. They loved the school. The theater one did transfer there after 2 years at a community
Many D1 football players take courses online in season so they can work at their own pace, study when traveling, etc. It’s hard to know what classes he’s taken and what he still needs.
