When I was at PSU, in my freshman year (showing my age) we beat Purdue and Glenn Robinson when they were something like 16-1 and ranked #5. So, it's storm the court time! All fun and games until Big Dog Robinson himself was jogging off the court in MY direction. I'm still alive and here, so obviously we didn't make contact. Big Dog was one LARGE mass of humanity!!!
Anyway, I love the storming of the field/court as part of the fun of college sports. I'd never want to see it outlawed but the above is the sort of risks you take.
