Just because one can throw a ball well does not mean they know layouts or coaching. Also, just because one understands the game does not mean one can drill or throw the ball well. I understand ball motion and layouts fairly well, but I do not consider myself a "tournament" bowler to the point of competing every week. I have people that I drill for that are in the top 2-3 bowlers in the state but they don't understand layouts not are they good at coaching. "Put what you think I need on the ball and drill it." IMO, think in today's game, it is difficult to find a person that can do it all (coach, drill, bowl)
