...of fans bring up ideas that are really impractical like surrounding the stadium with a Brick wall full of arches or some other facade. Such ideas while pleasant to entertain us are mostly impractical and not just because of cost. If a billionaire donor wanted to contribute the cost of $150 million you could do a really nice curtain wall expansion, add an office structure and sports mall to the west. But here are the realities that MUST be considered:

1) The stadium is built on alluvium above the Wasatch Fault.
2) Considering #1, you do NOT construct a big heavy structure out of even reinforced block and tie-back brick veneer. If you want that look you would need to go to an EIFS system that on such a large scale might cause some fire code issues and so not realistic. So nothing heavy.
3) Considering #1 and #2 above, you could do a glass on steel space frame curtain wall structure on separate foundations, With roofing and 5-7 stories of interstitial floor space on the west side for an office space, you could create a structure that looks similar to the Jazz arena. You could do that for around $150 million.

4) The least expensive overbuild would be to fill in the corners above the access ramps but on new foundations. I think you could add roughly 2,000 seats per corner as benches. I would love to see BYU's capacity increased to 70,000.

Again I think filling LES is about properly pricing tickets, especially on the lesser end and in end zones. The last thing people buy is concessions, but they buy concessions. If you are looking only at seat revenue, well $15 x 0 buyers is $0 revenue. But if the package is $ 7.50/Ticket x 1 buyer the revenue is $7.50. Since the concession average is let's say, $15/seat at that level, $15 x 0 Seats sold is $0 revenue. But $15 in concessions x 1 seat sold is $15. Total Revenue when a $15 seat goes empty is $0. Total Revenue when $7.50 seat is sold is $22.50. This is not Rocket Science. Its what Walter O'Malley learned from Barnum & Bailey and he applied it as owner of the L.A. Dodgers over 60 years. It is a principal that has never changed. Fill the cheap seats cheaply, sell a heck of a lot of popcorn, peanuts and cracker-jacks.
