WIU's pressbox is actually a real pressbox but it only seems to have about 5 or 6 little booths for broadcast. I remember Jeff and Phil talking about how cramped they would be next week. My guess was that the KVLY crew was an extra set of hands and they were told they could do it but not get a pressbox since WIU was on the hook for ESPN+
In the past, they have just not gone when another broadcast is on ESPN+ I guess they want to go the extra mile on this one for local broadcast.
