Thanks, GreenMonster. We’ve been working on pushing off more for a longer stride in response to the comments here about the video. However, in response, he now seems to be letting his arm hang down longer before initiating the throwing motion, which effectively maintains the poor timing. I think he’s just gotten used to his arm being “late,” and he’s adjusting his arm action because that feels right to him. Any advice on drills or other ways to get him used to what it feels like to have your arm in the right position at foot strike?
