Not to mention, when you go to games, you are held hostage to replay delays without seeing an actual friggin' replay! You are much better off watching the game at home where you can see about 5 or 6 different angles of a play 20 separate times than being at a game. UCONN/Global Spectrum needs to think about changing this policy to give fans in the stands MORE access to in-game reviews, not less.
Increased wi-fi inside the stadium would be nice. Like it or not, people love their phones.
Build up a standing room bar area over by the scoreboard. Rope off the #6 area as sacred ground. Then construct a patio area for casual fans to mingle that includes a fully stocked bar, table seating and a standing area to watch the game. If you can't beat 'em, join 'em I suppose.
To help with traffic, they need to relax the tailgating policies. If you allow fans to come much earlier (ex - 6 hours before kickoff) and stay after games (up to 2 hours post-game), this will help spread out the traffic waves. Making everyone funnel out as soon as games end only encourages fans to leave games early to "beat traffic".
These are all fairly simple fixes that would enhance the game-day experience for the fans that go to games regularly or fairly regularly. But yeah, more fans won't go to games until the team wins or we get into a P5 conference. Or both.
