I believe that every young pitcher should take at least two months off of competitive throwing. However, people need to understand that it doesn't have to be the same two or three months for everyone. But for most it will be in the end of July to beginning of February time frame. In other words within those 6 months.
Everyone should understand that pitching has risk involved. You cannot eliminate risk, but you can do things that will help. High velocity is a problem and can create additional risk. However in many cases high velocity gets the biggest rewards. Risk Reward, too much risk might create injury. No risk = No reward.
Probably still too early to call, but it looks like PitchSmart and HS Association pitch rules are helping to eliminate a lot of abuse. I think we only had one or two violations of the pitchsmart rules all year. We are talking about thousands and thousands of games.
