Replying to Coaching high school lacrosse

just got the opportunity to coach my old high schools lacrosse team. I graduated in 2008, was part of a dictrict champ team, 4 year varsity starter. I have a bunch of knowledge on the sport, but Ive never been a coach. i was wondering if anyone had any tips for me. for people familiar with lacrosse, i wanted to run a 231 when were being defended man to man, and a 222 and 141 in a zone. ive been an attackman my entire lacrosse career, so my defensive strategies are basically teach the defense what i hated. anything i disliked i feel like will benefit the defense, because ill know what i hated to see. thanks in advance.
