You let your team down, sure, but we all have. I don't think there's a person on this board that can honestly say that they have always come through in the clutch.
My issues with the 10 pin come and go. But its mostly to do with practice. You need to practice this pin. And when you set up to pick it up you need to make sure your body is angled along your ball path, which if you are shooting across alley, means not parallel to the foul line.
