re: Cal is allowed to do just about anything: GIF updated in OP

You must be trolling. There is no other explanation for you to keep this up. When, in any sport, is an individual who is not IN the game (player or coach or whoever) allowed to step onto the court/field/ice/pitch/diamond/track/etc and interfere with play. You might be trying to argue that its not a big deal because Cal did it to his own guy, but that fact is irrelevant. Someone who is not in the game is not allowed to interefere with play. I dont need to look in a rule book for that.
