Right now, it's open season on us. I am not suggesting that they answer every single idiot who speaks publicly. But I do think that they should speak once, for the record, and challenge someone to provide proof for their statements. There is none. If they either publicly back Joe once, or else throw him under the bus for good (which I'm not advocating), then maybe we get the public fires to die down.
At some point, the university WILL have to say something. They will either need to to properly honor Joe, or else wipe his name off of everything because he is the devil. He can't stay in limbo forever. Of course, doing the latter means that the Paterno name can no longer be used for fund-raising. No more Paterno Scholars, etc.
I'm rather surprised that the Paterno family hasn't forced the issue. Maybe they are waiting for their lawsuit to go to trial.
