On first viewing, this scuffle between the Utah Jazz Bear and a Cavs fan definitely appears fake. There's a camera right there the whole time to broadcast it on the Jumbotron of the EnergySolutions Arena. However, pay close attention at how hard the mascot hits the Cavs fan at the 1:03 mark, shortly after he starts charging him. Looked like a pretty solid hit. The Jazz destroyed the Cavs, 121-99.
