The student overflow is currently Pitt sideline upper corner, AND upper endzone corner closest to Pitt sideline. Although Pitt sideline upper corner I think is first priority for overflow -- perhaps they are switching the priority order of those around?The student thing is partially true, I'm sure. The overflow is currently on the Pitt sideline upper corner. They are probably just changing the overflow to the upper endzone, which is smart, since those are the least valuable seats.
If there are any seats that you never see on TV, it's the Pitt sideline upper corner. You will sometimes see the upper end zone on TV when they show a wide shot from the field level.
