Alabama kids play 2 years of Ball, FCS kids play 4. Almost every kid that starts at Alabama, if not all, are either drafted or brought into an NFL camp. Watch any NFL game and somebody is sent to the locker room about every 10-15 plays. Watched a NFL game about a month ago and five straight plays somebody was helped off the field, two of those were stoppage of play knee injuries, almost certainly ACL or MCL tears. I don't believe you will see high school football in 20 years. It will be a community funded sport not sanctioned by public school systems, schools wont be allowed to accept the liability moving forward when all the medical research catches up regarding head injuries and lasting affects. Many retired NFL players are coming forward with a lot of nightmare stories.
