It was one of the main sticking points in Villanova's upgrade from the Colonial to the Big East, and it looks like for now it will be the difference between them moving up to FBS and staying at the FCS level. According to the Phildelphia Enquirer's Mike Jensen, a vote on the Wildcats' move to the Big East has been delayed due to Villanova's preference to play their football games at the 18,500 seat PPL Park, home of the MLS's Philadelphia Union.
VUHoops.com talked about Pittsburgh's reluctance to having the Wildcats play there, and it looks like most of the conference was not happy about the situation either. Even with a stadium expansion to 30,000 seats as a possibility, some programs weren't 100% behind the idea.
There aren't a lot of other options in the Philadelphia area. One option might be Franklin Field, but it is an extremely old stadium without the modern amenities that Villanova fans would have at PPL. Citizens Bank Park figures to be occupied with Phillies games well into any college football season, and Lincoln Financial Field is already being leased by Temple.
So now, all we can do is wait until Villanova presents an alternate plan to the Big East.
