WIFI could add so much to the game experience, considering the ribbon boards and scoreboards are too slow and the people running them are not in tune with what's going on. Also, as was mentioned above, pregame, TV timeouts and Halftime make for PLENTY of time to use your phone.
WIFI can make the games better by providing:
Real time stats
Injury updates
Scores of other games
Talking to those watching on TV to see what an analyst says about any play
Replays of gameplay, because our video boards often won't show controversial calls or turnovers until after the play.
Listening to Tome leach and the rest of the UK network whenever you want
Chatting with other friends about the game that aren't sitting with you
These are just some of the many ways that the internet and phone service can enhance the gameday experience.
Todays youth(students) are used to getting info RIGHT NOW. When their ability to connect with others is compromised, they will stay home where they can see the game, interact with their network of friends and get the info they want instantly.
You have to believe that high quality WIFI would increase the student attendance as well as make the games better.
