I only bring this up as an comparative example, but C. has a solid setup for parking on gamedays. The closer to the stadium requires a permit. I could see USF doing this for most lots on the east side of campus that are not residential, from the library to the YC and north to the new stadium. Free lots further away (for USF, probably fine arts area, the Laurel area, and down to engineering area). I know there's also a handful of lots being added around the new rec fields on the southwest corner of campus, those may be the Park and Ride where Bull Runners can operate.
C. also set up those disposable trash cans over many of the grassy areas near the parking lots for tailgating (well at least they did 10 or so years ago when I went to a game there last).
