I played football growing up, and loved it.  My kids got into flag young, and both started tackle in 3rd grade as they do around here.  Both played 3rd and 4th grade and gave it up (I was scrawny as a kid, and they got that from me, so they were generally just getting pummeled and didn't enjoy it).  It didn't break my heart to see them give it up.  I saw a fair amount of concussions in those few years in other kids, and saw a high school player have to give it up after his 3rd concussion.
My older son is now in 8th grade and has to decide in the next couple of weeks if he wants to play high school football in the fall.  I'm leaving it up to him, certainly not encouraging or discouraging him, but won't be heartbroken if he decides not to play.
		
		
	 
Timely bump.  My oldest played freshman football this past fall.  He was one of the two QBs, and they each took turns playing a half.  Long story short, he suffered two concussions during the season and his football career is over.
The first one came during practice of all places.  The freshman coaches were...not very good, to put it mildly.  They didn't think the kids were being physical enough during the games, so they did a bunch of live hitting (I believe in excess of what high school league rules allow, but I believe freshman sports aren't official in MN, so there might not be any rules to break.  I'm unsure on that).  Well, they were doing full speed live hitting kick off/kick return.  You know, one of the most dangerous parts of the game.  My son, all 5'10" and 125 lbs of him was in the front middle of the kick return.  He runs back to set the point on the front line, turns, and some kid with a full head of steam from the kick off team plows into him.  Head hits the ground, gets up dizzy, headache, etc.  It takes him longer than the minimum to come back (and I held him back from a couple of steps of the ptotocol, because I didn't want him rushed back).  He misses two games.
Comes back for the last game of the season.  Plays QB in the second half.  Less than a minute left of a blowout loss.  Coach calls a pass.  He moves in the pocket, can't find anyone so scrambles up the middle.  Sees a trio of defenders so he slides.  Big LB almost twice as big dives into him as he's sliding, and his head hits the ground again, violently, and I'm there to watch as he lays on the ground motionless for what seems like forever.  Learn later he blacked out.  Started the process over.  No games left, so nothing left to miss...except he is held out of captains practices and "warm ups" for the basketball season, so he misses the start of that.
No more football in my house.
