Pass interference - change in NFHS rule

[JDLJ]

If the action is before the pass is thrown you might have holding since this action could affect play by influencing where the ball is thrown. Once the ball is in the air, if the action is away from the pass, it is no longer pass interference and, if it's not flagrant holding (bear hug and drag to the ground), I think the idea behind the rule change is to let it go - it's action away from the ball that does not affect the play. Merely changing a call from PI to holding would not be a reason to change the rule.
