Well, I am in a fantastic Div III league where my team is very overmatched. However, the past two seasons they were in Div IV where they dominated. In those seasons, my center averaged only 0.6 and 0.7 blocks/game. My best shot-blocker is my PF with only average inside defense and average shot blocking. Blocked shots seem to me to be random events that don't have much to do with player skills. That is why I am questioning the wisdom of spending any time on additional training. Seems like the training time would be better spent on other skills.
