So your talking about D line play, Thought you were talkin bout O-line.
Good drills to do for your son with d-line and these came straight from a guy who's probably going to win 2A this year(mabey lol). We taught this on the high school level but it's really easy. Line up 2 D linemen across from each other or all your d-line.
Bout a 45* degree bend with your arms away from each other, pretty tight.
Always stand behind the opposite guy that is doing the drill so you can see tech.
Have the d-lineman you are looking at while standing behind the other put his hands on the ground, fingertips. Now they will be both lined up on their knees for this drill.
On command call HIT! having the D lineman with his hands down fire both his hands straight out into the guys numbers, Thumbs up. Grab cloth and do not release until you give a READY! call. On ready he puts his hands back on the ground. Hit, He fires his hands straight out back into the guys no.'s thumbs up and grabs cloth, Don't let him release till he heres your Ready call then hands back o the ground. Start slow but when he gets it down, Fire it at him quick. READY, HIT. LIKE A MACHINE GUN. Your teaching him the most important thing he can learn as a d-lineman, To use his hands and get seperation from the o-lineman and keeping him from getting into his body.
