OK I've put a bit of thought into it and decided that if you want a fair totally unbiased system to decide the outcome then you cannot use any team or player stats as this will inherently favour one team over another, it's unavoidable. I know you are keen to avoid the 'dice decides game' principle but when all is said and done that is what a game will usually come down to. A gfi, dodge or a block dice can be the difference between a win, draw, or loss. So does the penalty rule really need to deviate from rolling dice and it basically coming down to luck? Let's be fair if after 16 turns the game is tied then there isnt that much difference skill wise between the 2 coaches so it probably would be a bit of luck that swings it one way or another anyway.
So here is my penalty suggestion based purely on rolling dice and no outside influences that would favour one team or another. I do have a few idea's to make this more complicated or incorporate player skills/stats but the basic idea is this:
There are rounds of 5 penalties each. During each round each coach rolls 3 block dice at the same time - a pow means you score, a skull means you save an opposing pow and nothing else counts. No dice 'roll over' to the next round and the person who scores the most after 5 rounds wins. in the case of a draw after 5 rounds then sudden death comes into play.
Example
Coach A rolls, push back,both down and pow - Coach B rolls, 2 push backs and a defender down. Score after round 1 is Coach A 1 and Coach B 0.
Coach A rolls, skull,both down and pow - Coach B rolls, 3 push backs. Score after round 2 is Coach A 2 and Coach B 0.
Coach A rolls, 2 both downs and pow - Coach B rolls, 1 skull and 2 pows. Score after round 3 is Coach A 2 and Coach B 2.
Coach A rolls, 3 pows - Coach B rolls, 3 skulls. Score after round 4 is Coach A 2 and Coach B 2.
Coach A rolls, 1 skull and 2 defender down - Coach B rolls, 2 pow and a defender down. Score after round 5 is Coach A 2 and Coach B 3.
Coach B is the winner in this example.
I know it still seems like a bit of a dice roll of but I think it might work and add a bit of excitement into the penalty shoot outs. If you relly wanted to include players then you could make it that you nominate your 5 penalty takers/keepers and their skills may impact on the dice: eg. kick skill allows you to reroll the dice, tackle converts defender down to a pow, wrestle converts both down to a skull. Block does nothing otherwise dwarf longbeards would become to good at taking penalties.
Hope I've explained myself OK and feel free to let the trashing of my idea begin
