Why is stoppage time a thing?
Why don't they stop the clock when the ball isn't in play?
time is also a tactically element (albeit a bit dirty)
time wasting can be useful in delaying play and to try and stop the oppositions tempo.
time wasting does sometimes get punished with cards (yellow cards mainly).
the world cup did try to combat time wasting with way more added time. There were alot of games with more than 10 minutes of added time.
I can understand where you are coming from. Plays like a buzzer beater are really hype
