Personally, I fall somewhere between "Penn State should cancel this weekend's game" and "Penn State should forfeit the rest of the season."
Penn State is, first and foremost, a university. I think it's safe to say that the manner in which they've handled this situation, beginning in 1998 with the first accusations against Sandusky, stands as evidence that as an institution they've lost sight of that a bit. By cancelling this weekend's game, they'd be sending a clear message that they understand the gravity of this situation and would also be expressing to their fans and alumni that they're committed to taking whatever steps necessary to ensuring that something like this never happens again. More importantly however, is the simple fact that in the wake of everything that's been revealed in the last week, the Penn State community is simply in no position to guarantee that they can safely host an event of this magnitude. McQueary, for instance, will not be in attendance this weekend because of the sheer number of threats that have been made on his life. Two nights ago, students rioted in the wake of the news that Joe Paterno had been released. What happens if Penn State falls behind 3 touchdowns and the crowd becomes unruly? Do you think those same entitled, drunken 19 year olds are going to behave with grace and charm? Do we suddenly expect them to recognize the magnitude of the situation and not act out? Isn't it much more likely that they continue to feel that Joe Paterno has been the subject of a grave injustice, and with him at the healm, Nebraska wouldn't be winning?
Put simply, I can think of a handful of reasons why Penn State should cancel at least this weekend's game. And the while I can see the point about hot dog vendors/parking attendants, it doesn't feel like a big enough consideration in my mind to cancel out the other concerns.
