High school and collegiate wrestling don't have submissions. The match ends earlier than the time limit if there's a pin. I know people here say in wrestling you need to put both shoulders onto the mat for approximately 3 seconds, but that's not true; once both shoulder blades touch, it's a pin. At least if it's in an obvious pinning combination. Referees won't call a pin if both shoulders touch the mat in situations like when you're rolling.
There's also technical fall - the match is stopped after you get up by a certain number of points - I think it was 15 when I was wrestling and coaching, but it might've changed. This is all NYS high school rules, and NCAA is pretty much the same with some subtle variations like points for riding time.
Do any BJJ tournies have some sort of technical fall rule (match is stopped once you're ahead by a certain number of points)?
Edit: BJJ stops when you say something like "I give." That's usually tapping or being choked unconscious
