He appears to be mid 60s. I’m not entirely sure he’s an old school coach, but wanted to know what to say if he was just in case. By old school, I mean the ideas of…
Come to a balance point and stop
Land in the “power position” showing the ball to CF
A short stride (YES, I have literally been taught this)
To stay on the rubber
To bend the front leg, to throw low in the zone
Examples like these, which completely ruined my mechanics a little over a year ago (I’ve yet to recover, as many members on this site can see by my current mechanics).
