Guys - what do you think of this idea? We've all had coaches who want to call the game. They yell things like "traveling", "carry", "foul", etc. How about we all agree to do the following. Whenever they yell out a call, we get to yell out a coaching instruction at their team. For instance, they yell "travel", we yell at their guard, "switch". Or, next time they're on offense, we yell at their center "post up", etc. You get the idea.
When they ask us what the heck we're doing, we tell them that every time they try to call the game, we're going to coach the game.
I think it's worth a try.
WARNING: if Larry Craig is coaching, just ignore him when he yells "that's a reach" or "over the back".
