anything you would have done differently now that your sons are Jr's or Sr's where were your sons in 9th grade?
Gunner,
Great question. I honestly don't think there's anything my son, my wife, or I would have done differently in regards to son's velocity development (which is what OP was asking, and I think you're asking?) through the HS years. Ironic, because son's velo path was about as slow and non-exciting as it gets.
These are things that I know did not help him with pitcher development, especially regarding velo. But with that in mind, these are also things that we would not change or do differently:
1. Playing basketball from October until mid-March for 9-years; did not help with pitching. It helped him become a 6.9 runner, but it delayed his ability to throw 90mph off the mound, as he never had time during basketball season to throw, and certainly no time for an off-season throwing program. Basketball was son's choice.
2. Sending son to boarding school 6-hours from home at age 14. With no car, or reasonable off campus transportation son was never able to work with a personal pitching coach during the high school years. Or ever for that matter. Boarding school was our choice.
3. Spending Junior year of HS living abroad in Europe did not help his pitching development. Did wonders for his French though. Spending year abroad was son's choice.
4. Consciously sending son to a HS with an anemic baseball program did not help his pitching development either. For example, they never practiced on Fridays (???). We chose the school for it's academics, not athletics. Our choice.
So Gunner, in the end, yeah there's lots of things that I guess son should have done differently in order to be a better pitcher today but would we do them differently knowing all this? NO.
As parents, wife and I have always tried to err on the side of encouraging son to pursue LIFE, in addition to the BASEBALL LIFE. Encouraging him to play multiple sports all through HS and to spend a year living abroad at age 16-17, were things that in no way helped son in his quest to become a pitcher, but we believe they will help him be more prepared for the 40-years post college, not just the 4 at college.
It's a fine line to tread Gunner. All choices have pros and cons. Researching both sides of each choice is highly recommended. The choices ultimately dictate the outcome.
