Thanks to Geoff for the shout-out on my writing on fan speech. I wanted to post a quick response.
First, while I agree it would be disgusting for opposing fans to taunt players about the specifics of child sexual assault, I am not as sure that taunting players about the overall scandal at a university and football program of which they are a part would be uncivil. Especially if the message is that PSU is not the holier-than-thou place it pretended to be for 60 years. A little bit of schadenfreude is a core part of cheering speech. Geoff also is right that the NCAA, Big 10, and schools cannot do anything about this (exception, ironically, my alma mater).
Second, I do not have a problem with Penn State fans overdoing it with praise for the involved school officials. I expect it and, in fact, welcome it. One reason to protect speech for uninformed or offensive ideas is to expose those ideas, and those who hold them, to public attention and ridicule.
