was a student, and haven’t since then beyond verbal jawing which is gonna happen regardless in rivalry games. At least up until the PSU game this year with the PB&J throwing. And even in that game you can see video after the game of both teams peacefully walking through the tunnel and even some chopping it up with each other as they walk to their respective locker rooms:

We aren’t the only school with a single tunnel. For example Spartan Stadium has a single tunnel as well. There is already protocol before the game and at halftime with teams taking turns heading in. I’d expect going forward to be much more strict protocol with additional security.
