Retractable roof stadiums are ideal especially for NFL. For college I prefer games outside. Seatbacks are dumb for college, I like bleachers where students can stand on top of them of or even better don’t have any seatbacks or bleachers in the student section like WaGriz. For NFL I want to see the highest quality of football which is degraded with bad weather conditions. For college football I want to have a strong environment with a lot of energy which can exist in a dome but isn’t that common at least in the Big Sky.
