That comment should not have been downvoted like it was, there is a real problem with concussions and the science is clear. If I had a son I don't think I would let him play football.

Although my brothers and I played football (one of them professionally), I share your concern about concussions. If football doesn't solve this problem in the next decade it will deserve its eventual obscurity.
