I see nothing wrong with people praying. In fact, it is very admirable to see young kids doing it. Also nice to know they are not praying for the win, but for nobody to get hurt. The problem I have is with doing it on the mat--especially after you have put your leg band on. It is time to wrestle then. If as you say it only takes 30 seconds, in a 16-man bracket if every kid did that, it could prolong the tournament 2 more hours. I know not everybody does or will start doing this but I just think there is plenty of time right before you go on the mat to pray.
