In judo if you land a throw where your opponent lands flat on their back it is an instant win. The reasoning is someone who doesn't know how to fall on concrete is dead or unconscious if that happens to them, without mats even a trained person may be fucked. A good takedown can be over in a second.

For multiple serious opponents I think hard throws is probably your best bet.

Or...

ya if they're trained they can do that too but even better by holding those positions better and takinf their time to do all of the above.
