To turn the arena around? Haven't they learned anything from the NCAA tournament? Granted, the NCAAs have 16,000 and the Utah/Weber game will have 4,000 at best, getting people out and reopening the arena in time for another game in 1 hour will stink for BYU and USU fans. 

While the issue might be that fans don't want to watch both games, (I certainly didn't stay to watch USU and Weber after seeing my team get smacked by Childs last year), the sticker price of $60 for lower bowl is the true issue, IMO.
