I would suggest he play a different sport until he grows some. That large of a weight difference at that age could be dangerous. If he runs track or cross country he will keep in shape until then. Sometimes you have to play the cards God dealt you.

How about playing safety/wide receiver? Maybe his size and speed becomes an asset. Also focus on tackling techniques. Check out the skills library: http://www.weplay.com/youth-football/drills Good luck!

I would second TJ's note on tackling technique. My son is 79 lbs taking on kids up to 120 lbs in Pee Wee. He learned long ago that technique (low man wins) gave him the ability to take anyone on, and he does so with abandon. He plays all out, which is the only way to do so safely (thinking about getting hurt or being the smallest is the fastest way to an injuty).

u should go for there legs.That the best way to tackel bigger kids and the bigger they are the harder they fall

I agree with Mr. Bennet my 80lb son plays in a league that goes to 105lbs and he plays Free Safety because he is one of the better tacklers on the field. His trick, no fear, don't stop and put the shoulder pads on the thighs. He happens to also one of the starting RB's and his size is actually an advantage especially running inside. The LBs can't even see him until it is almost too late (he is shorter than most of the lineman) so he plays a bit of hide and seek with them. BTW - I am not the dad/coach that put him in these positions - I just coach Special Teams - so this isn't a "Daddy Ball" situation.

Aim for the shins. YES more times then not it is going to hurt if he is hitting a 150 pound back at full speed. Hitting someone that much bigger head on at the thighs is probably not going to work. Your son will probably take a knee right in the head and get run over.

nobody no matter how big can run without their feet. Tackle below the knee keeping his head across the runners legs. LOW LOW LOW

My daughter is a 58lbs safety and WR. Her brother is a 105lbs QB and Linebacker. Needless to say that was an intresting matchup during Tackling drills. At first my daughter was getting run over by the bigger and stronger man. First i told her tackling is all about attitude. if you think big you hit big. Then i told her my secret. Watch the hips. Put your facemask on the ball(to keep the head up). This automatically puts her shoulder on the runners hips. and run through the guy while wrapping his !Legs! with her arms. After she got the technique down i told her to keep practicing with her brother. You Get What You Train For! During the games, She had no mercy and tackled 80lb to 130lb Runners with no mercy. Another thing she said is that it hurts less if she is the one giving the hits instead of taking them.

I would be very careful about trying to teach ankle tackling. While it looks very cool on Sunday (NFL) it is also the best way to miss a tackle. At this age stick with the high-probability tackle - hit center mass. Head up, shoulders down, aim for the middle of the body. if you can catch an angle the thighs and knees are low enough the kids can keep their feet in the ground (no diving, no spearing) and still bring a stronger back down. Head-on? aim for the hips/gut. Always wrap and keep driving the feet. For a bit more advanced kids that have the techniques down, start teaching how to explode into the runner - not just running through - but exploding them off their feet - coil up from the hips and teach the RB a lesson - "size doesn't matter".

Remember typically the smallest player on defense is the safety, he is also the best tackler
