People need to quit acting like the 50k expansion number being thrown around is some upper ceiling that we can't break through. If we are selling out the stadium, the money will be there to expand it to whatever the heck we want. The stadium could be 80k if we needed it to be. All we would need to do is add upper decks all around, and enclose the bowl by the athletic center...would that cost a lot of money? Hell Yeah, but if demand warrants it, we would have the money.
I think the "image" of a full stadium that is of high quality is much more important at this point than having a 40k seat stadium with 10k empty seats. Plus, I may have missed it, but where are the people mentioning the shortsightedness of SMU building a 32k seat stadium only expandable to 45k...
