Can somebody explain to me why Indiana fans storm the floor.

Because they can and it's really easy to since there's no barrier between the student section and the court. At Rupp, there's a rail, stairs, some press tables, and tons of security. Most arenas that don't have multiple barriers separating the crowd and the floor will have students rush the court.

If UK students had the chance to storm the court after a big win, they would. Celebrate with players and stand on Rupp's floor, who'd pass that up?
