While WVU fans have made some decent point on this thread (for example I checked online and confirmed that its series with East Carolina has largely been on a 2 for 1 basis), that statement seems to be incorrect. I can recall friends in the construction and architectural trades that previously told me that the stadium was designed for expansion. I do know the stadium has been expanded from its original 30,000 seats to 38,000 (a client of mine did the expansion work). An online search I did a few minutes ago found articles indicating that the stadium was designed to be expanded to either 50,000 or 55,000 seats.
That does not of course mean that MU will obtain funding for such an expansion, and, yes, MU generally hasn't drawn that well in recent years, but the losing seasons posted by the Mark Snyder regime didn't help.
