The timing of the whole thing doesn't add up either...
Pitt played Buffalo (in Buffalo) at 3:30 that day. The game was over at 7PM. I have never been in a college football locker room, but I imagine that they are in the locker room for about an hour until they leave the stadium, so it's now 8 o'clock.
According to mapquest, it takes between 3 hours and 40 minutes and 4 hours and 30 minutes to get from Buffalo to Pittsburgh, so lets say that it was a 4 hour commute home (which is being generous because they are traveling by bus, which generally takes a little longer). So now it's midnight. I would imagine that they also stopped to eat at some point, given the time of the game.
According to this article from the Huffington Post, the incident happened around 12:30 AM. The team would have had to haul it back big time (and not eat) in order for the players to be in Oakland during the alleged time. http://www.huffingtonpost.com/2012/11/0 ... 63610.html
I won't lie, I am a miserable suffering Pitt fan, but this all sounds fishy to me.
