Short answer, anything but football (that later changed, with a bit of a caveat).
My kids all played sports - both of my daughters and my sons played lacrosse, soccer and basketball, as well as track/cross country for years. Neither son ever expressed interest in football mostly b/c of not liking the tackling. Good, b/c I was vocal about not wanting them to play anyway.
But then….My older son, a three season athlete in h.s., was approached on the soccer field freshman year of high school by the football coach when their kicker was injured. Up until that point, he was planning on playing lacrosse in college. He ended up getting recruited as a kicker/punter by a smaller D1 school and was the team’s starter all three years (one year was lost to pandemic). He never had a sports injury in any sport but he did have a concussion around 9 y/o when he fell outside in our yard slipping on wet grass!
Younger son switched to rugby in h.s., a sport that did make me cringe. He continued to play club rugby in college but his only injury was a torn hamstring. I admit rugby made me nervous but it did wonders for his very low self-esteem/confidence, allowing him to feel like he had something of his own after being in his brother’s shadow growing up.
My daughters weren’t as competitive with sports as my sons. Oldest played soccer thru high school. She did play one season of lax in h.s., did receive a mild concussion after getting hit in an illegal play. She quit lax after that season-ending injury. My youngest switched to tennis in h.s. and continues to play club tennis now in college.
My sons have always been golfers and that is their sport of choice now as 20-somethings. My older son also plays in an adult soccer league.
