A&M is just so stupid. In '09, they averaged 77k per game in a stadium that seats around 83k. Now they're spending 450 million to have something bigger and shinier than Texas.
I've been to A&M twice for conference games, once against "rival" TTU. The stadium was far from sold out for both games. Now they want to add another 20k seats? They'll sell that sucker out for a few years probably, but once the SEC shine wears off, they'll be back to ~85k per game or so.
