Funny that you use that example. That's a classic example of something that's achievable in a trustless manner. If the address has no outbound activity for x time, transfer assets to beneficiary. Something like who wins the sportsball event would have to rely on a 3rd party oracle, of which there are many, but for the right price any of them can be tampered with.
I wouldn't want to rely on a dead man's switch pretty much my whole live. But you are right: There are many more examples. The one you mentioned suits better.
