I have a son that is 13 and in the 8th grade, he does not turn 14 till July. That means he will not be 18 till the July of his Senior year, so he will be 17 basically his whole Senior year. How much of a impact do you think that will have on him football wise? should i of held him back? he makes decent grades and is above average in size and skills to most 13 year old's. I see alot of kids already 18 or going on 19 in their Senior year is why im asking. Ive been thinking about my football days and is was like night and day from a Junior to Senior, i turned 18 in Oct of my Senior year. Thoughts?
