You’ve got to move your feeling in accordance to the play. Have a pulling guard? Ok, move your opposite foot first slightly so your 300 lb behemoth doesn’t crush it and so your timing lines up with him getting to his spot.
Is it a power run? Hard drop step to the Rb... off tackle? Get to the hole
All while getting the ball cleanly.
All can be taught, but I think if you teach the kids at a young age, it can stick with them. I think shotgun offenses in peewee and 7th/8th grade football are dumb because you don’t have the strength to play spread.
Anyways, just my opinion
