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.
A great comment on this from Jets linebacker Bart Scott back in 2012, "“I don’t want my son to play football,...I play football so he won’t have to. With what is going on, I don’t know if it’s really worth it. . . . I don’t want to have to deal with him getting a concussion and what it would be like later in life.”
In general, commentators are too quick to delete downvoted comments. Often, a comment that is initially downvoted will return to positive within a day or so, if only it is left alive.
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.
