1. When a wrestler throws or slams another wrestler I think they say the knee of the offensive wrestler has to hit the ground before the other wrestler... What about when both wrestlers leave the ground and land at the same time? Is it just a judgement call? And wouldnt that be potentially dangerous if they are both in the air so no points should be awarded?

2. If the slam is ruled as ok, I can see if they take down is awarded but if injury is involved would the ref go ahead and award the pin?
