I'm happy to report my real life coaching experience worked out much better than my fantasy coaching has ever been. Allow me to indulge in satisfaction for my team (and my son's team) taking home the championship 19-6. I hope everyone has a chance to share such a moment they treasure at some point. I've been fortunate enough to do this in academics with a math team I tutored, and now with a kickasd bunch of kids who were told they would never in a game.
I tried to teach real Blood Bowl to my son in the late 90s, but he soon changed it into a fighting game, with the blue pieces trying to literally crush the red ones (when they weren't just thrown out the windows, or chewed). So I made the rules a bit simpler, pieces attacked other pieces by rolling a dice and the higher score won, eliminating the opponent. And the ball was changed in a marble we used to "shoot" from a distance players that have been attacked (and killed) outside of melee range. He loved it, and he called it "I win you win". When he got to an age he could have really understood the game, he totally lost interest. Meh.
