I go to a fair amount of games in different stadiums, and I'll tell you there's a couple very, very simple changes that have to be made.
They have to drop the attitude that you're at this game, and nothing else matters in the world of college football. We are now conditioned to have scores and highlights constantly throughout watching a game on TV. This flashing Top 25 or conference scores once a half just doesn't cut it. Especially when you've at a game watching your team crush an FCS joke, and they can't be bothered to give you any idea what's happening at a game between top 10 teams. Considering how much more down time there is with replay reviews and TV timeouts, it's a joke.
It's a hold-over from the days when you got one college football game on TV, and you got the rest of the scores in the Sunday paper the next day.
It's also the amount of information you get watching a game on TV now that you don't get live. Things like player stats, those things like "First six drives: 19 yards, Current drive: 74 yards" or whatever the stat people on TV put up to help describe the story of the game. We are accustomed to getting way more data and information with our sports. Hell, I remember watching boxing back in the 1980s, and they didn't even put the round time in the corner until the end of the round. That's insane to think about watching a fight now without knowing how much time was left in a round.
And the thing is, everyone now has these magnificent video boards that they use to show ads for the local HVAC company. The stadiums are perfectly equipped to bring the experience into the 21st century, there's no major investment needed.
1) Find a place to run a constant scroll of other scores and notes, just like the ESPN bottom line. All the time.
2) Every time there is a lengthy stoppage of play, they need to go to a feed of a NFL Red Zone type programming that is jumping from game accross the country and showing highlights or even moments live.
3) Every time a player has a carry or a catch, put his picture up on the board with his game stats
4) Regularly put up stats and factoids on the board for anything notable about the progress of the game.
Of course, making sure you have wifi/data service also helps in this regard.
They now make anyone attending a game sit through interminable TV time outs, plus replay time outs, and scheduling non-competitive games are common. Meanwhile, there are 10+ other games on at home. Stop making people feel like they are totally missing out on the better part of a day of college football to support their team in a 50-point blowout.
