If you read the article, it says that the 6th federal circuit made a ruling in 1997 banning this sort of activity. The 6th circuit, sadly, is Tennessee's circuit, and that means that this ruling is controlling. Fighting this in court will be a waste of money, regardless of how wrong you think it is.
I don't mind observing a moment of silence, in lieu of someone else telling me how to pray. I know this will be an unpopular opinion, but consider it in reverse. What if a Muslim was praying to Allah on the field, I bet the Christians who feel this sort of thing is ridiculous would have a total different opinion then.
Again I say that I have no problem with the prayer in general, but every time I have been to a UT game I have wondered how long it would go on before it was legally challenged.
So many people pretend that they would turn their back on the University for changing a denominational prayer to a moment of silence (so you can pray in your own way), but I don't see anything wrong with it. They aren't removing God from anywhere, he answer's prayers, you don't have to have someone else pray for you to talk to him (unless you are Catholic, but these weren't Catholic priests praying at UT).
Just my two cents.
