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.
If teams don't play to win, and collaborate instead of compete every sport will be boring while maximizing "points" but loosing viewership.
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.
