Thanks for the responses.
looking at projectables -
I'm a big guy 6'3" 250+( getting softer as I get older) I Don't think he will be as big LB wise- I was 5'11 180 when I graduated HS then grew in college and a little more on the military. at 21-22 6'3" 215. but I think he may get as tall.
Grandpa was 6'2"205.
2012 Brother is 6'1 205.
2019 is 6'2 180 now after this summer of weight room. added 10 lbs. Looking forward to the return from college this winter and 5am weights.
No phones at field. period. They stay in the car.
Not really a medical expert, but i've heard that your child's height has something to do with your wife's dad's height as well, all things being equal.
