The obvious result (to everyone but the creators of the rule I guess) is that, if a game is tied near the end of regulation, it is best for both sides if the game goes to overtime. There are 2 points available for a game decided in regulation, but 3 if decided in overtime. I assume both teams would sit quietly and wait for overtime if it were tolerated.
Speaking of NHL and weird rules iirc there's an emergency goalie that can be pulled out of the crowd to fill in for either team.
> Feb 22, 2020 Zamboni driver for the Toronto Marlies and emergency backup goalie David Ayres makes his NHL debut at 42 years of age, stopping 8 of 10 shots to give the Carolina Hurricanes a 6-3 win, all while stealing the show in Toronto.
(Game 1 of the 2023 Eastern Conference Finals featured four overtime periods; and the tie-breaking/game-winning goal was scored after 139 minutes and 47 seconds of total game time, at 1:54 am EDT.)
If it's tied near the end of regulation, your expectation value is 1. But if you and the other team wait it out and let it go into overtime, your expectation value is 1.5.
This is why all teams don't always play for a draw and only go for victory only on minimum risk. This kind of cooperative behavior is awfully close to match fixing and likely to get banned / fined by a competent league (one that wants to make money).
Soccer has its share of embarrassments like the CONCAF game in the article or the disgrace of Gijón in 1980, usually this happened in national games (not much money), modern clubs play to win like what FC Mainz did with Dortmund on Saturday, because playing to win is why crowds watch and that what makes money.
