So find myself on the other side of this issue. After a few years of pestering by the school I've made the tragic mistake of saying yes to coaching the high school Team. So I totally expect when I line up the pitchers and have them throw I will see a stable of HE pitchers. So do I become the coach we all like to complain about or should I brush up on all the outdated terms like paint the line, elbow to the target, slam the barn door. with only a few months to work with and no desire for warfare I think I'm going to have to grin and bear it.
BP, I've never coached fastpitch other than rec and stopped 4 years ago. But I think if I were the HS coach with different styles on the team, I wouldn't do much if any mechanics/fundamentals coaching, but would work with pitchers and catchers on strategy: figure out the ump's zone fast, then read each batter, try and get the first strike, keep batters off balance mixing speed and location, etc.
