Sounds more like a ref issue then a coaching issue. I see nothing wrong with teaching a kid defense (not focused on enough) & how to use warnings i.e. false start warnings & stalling warnings. IMO, if your up by several points, your job from that point forward is not to get caught & protect your lead, especially if you are in there with a dangerous opponent. Stalling may have been a big compliment to your wrestler twisted sister. Sorry it didn't end in your wrestlers favor.
