1st teach them a stance!!! You don't want to have a bunch of kids standing straight up and down.
2nd teach the dbl leg
3rd teach them to sprawl and cross face. That way they can drill them together.
4th teach them how to line up in referrees position.
5th teach a stand-up
6th teach one breakdown (arm-chop) and a half.
Assuming 2 moves taught a night along with some review time for moves learned earlier, you should be able to get something in from each aspect of a match by the 1st dual
Good luck!
Oh yeah, as far as the timing of the season, I just wish our District had Middle School wrestling. It would be nice if our freshman came in knowing the above techniques so we wouldn't have to start from scratch every year!
