Off topic kinda:
For tryouts this year we bowled for 3 straight days. 6 games a day and each day was a different sport shot ranging from a dry/short shot, a medium shot, and a shot with lots of oil. Kept a running score.
You also had to meet with the coach individually and you did a little skills test, which involved shooting your ball threw a pair of cones set at the arrows, between the cone and gutter (you had to hit the 3 board or you were going to hit the cone) And then there was 10 shots at the 7 pin and 10 shots at the 10 pin.
For the skills part you got extra pins added to your score. Took the top bowlers (for the exception of anybody that didn't seem like they were going to be team players or had anger problems that be harmfull for the team.
Far as our coach goes, WELL he's not much of a coach it seems to me. He oils the lanes for us and thats about it. If you have questions about your shot he will watch and help you. But i think his way of thinking is if you made it threw tryouts, your good enough you shouldn't really have to be coached.
He has taken our team to 4 national championships. BUT when you had a stacked team like he did i don't think it would be hard, people like jeremy sonnefield (Mr. 900), Derek Sapp (who is on tour now), and three other guys who could have played for any school they wanted too, who needs a coach?
The more you understand the equipment the more you can understand the game.
