At VT, we expanded the side lines and put down a firm surface at request of the networks because the previous configuration didn't allow full mobility of the sideline camera-boom-mobile (I'm sure there's a different name for that). They suggested we be on TV more if we did. I haven't taken note if the sidelines at Folsom allow for that, or if new technology has made the sideline width/surface issue moot.
There is not room on the sideline for the camera on the cart configuration. Thats the camera that usually gives you the tight shot of the QB at the line. The side line camera guys are shoulder "ENG" cameras. You'd have to take out a few rows to make enough room for that camera possible. There are other college stadiums that dont have the room for it either.
