Thanks for the credit.
Alternative shoot-out approach: follow the format of the NHL (three shooters from each team, alternating as in hockey, with additional shooters as needed until the tie is broken) - but with one key modification: the shooter gets the ball at mid-field, the defending team gets a defender at the top of the box, along with the goalie. Once the ball is touched by the shooter, but not before, the defender can move. Defending team must alternate defenders in the same fashion that the offensive team alternates shooters (no repeats until you’ve gone through the entire roster, unlike the goofy Olympic-TJOshie-against-the-world rules).
Two other major modifications:
Get rid of the stupid yellow card (no immediate consequences) / red card (death penalty) system, and replace with a penalty box (minors, majors, and game misconducts) as per hockey.
Allow (hell, encourage) the use of the arms to advance the ball or propel shots on goal. No carrying or trapping with the hands or arms allowed - those would result in lost of possession - but thwacking the ball to advance it, pass it or shoot it would be perfectly fine.
Soccer is only the world’s most popular game because it’s the world cheapest game (you’re not going to be able to outfit a football team in a village in Zambia), not because it’s the world’s most exciting game. American has a history of taking crappy sports and making them interesting (see: cricket, rugby (although I wouldn’t say that to the face of a rugby player)) and making them into sports worth watching - we should take it as a national mission to do that to soccer.
I believe your shootout scheme is very similar to something the old NASL tried in the 1970’s as a tiebreaker – that was still a one-on-one with the goalkeeper, but the attempt started at the 35-yard line (which they put in to replace the centerline for offsides) and the players had 5 seconds to shoot the ball. I recall a lot of them would toe-lift the ball immediately & dribble the ball in the air on the way in to get the goalie to commit.
The problem with the penalty box approach is that 11 vs 10 for short spurts really isn’t all that much of an advantage, unlike in hockey where 5-on-4 is a big advantage.
And if players accumulate yellow cards over a series of games, they are suspended for a game, so there are indeed immediate consequences to getting a yellow card.
