Tear down the press box, but leave the supports. Install a 'mechanical' ribbon just above the upper deck around the entire perimeter. A 'mechanical' ribbon is a robotized camera placement mechanism. It's a two function system: position the entire set of cameras and manipulate the viewing (e.g. zoom) of each of them. This would provide real-time, 360 degree video or stills from any position in the upper deck. Combined with the adjusted viewing features, it'll be the opportunity to view any angle on any play. Furthermore, it gives the relocated press box unlimited replay options from above.
So, imagine you're on your phone and you want to view the supposed David Montgomery's fumble at the Liberty Bowl (yeh. I know. It was the Liberty Bowl and not Jack Trice, but you get the idea). Now you'd be able to do it 360 degrees, frame-by-frame. Sure, additional cameras at field level would be ideal. Bottom line: use technology to usurp huge construction costs. Also, I'm sure the media would gobble this up.
