Football is a contact game and a violent game. I appreciate the effort to limit concussions and brain injuries, but I fear that football could be outlawed at some point in the future. It could happen.
There are many activities our life that might cause injuries.
If you are too fearful of injury, then don't let your child play.
I never played organized football, so I can't really comment on playing or practicing and the threat on injuries. My son played some, but never really got into it. I was never going to tell him not to play, but I wasn't too upset when he dropped it for good after his freshman year in high school.
He was really into baseball for years but now wrestles exclusively. But that sport has its own injury risks.
