Fwiw, i played ball thru HS.
On the kickoff team in 9th grade, I got trucked 1on1 tackling the other teams bowling ball of a RB who returned kicks also. Ran me straight over head to head. They woke me up with smelling salts because i was out cold....
I missed the first 2 snaps om defense directly after being unconscious and begged the coach til be put me back in on 3rd down. Played the rest of the game. Concussions arent nearly as bad as they are made out to be these days. They have wussified football because Junior Seau and a couple other dudes played pro ball forever and did so much brain damage that they had CTE like Muhammad Ali. I would let my kids play ball thru HS and college with no worries.
