I don't know the breakdown with seats in the 100-200 levels/upper deck sidelines/upper deck endzone sections to know an effective way to section it off, but whatever you can do to drop it to around 42,000 and it will be a packed house at least through the first two months of the season.
Give or take, there are approximately 33,000 lower bowl "regular" seat, 27,000 upper level seats and 8,000 club/box seats.
