I'll stand by what I have always believed, pin them when the chance presents itself. If you are wrestling at a caliber that you have to worry about not getting enough mat time or practice in tournaments, it sounds to me like you are getting ample mat time and practice in practice. This is just my stance and in no way would I accuse a wrestler of being a bad sport because they, their coaches or their parents think that they need to get more mat time or practice in tournament matches. That is their choice and if they do it in a sportsmanlike manner, more power to them.
