Ok, now that I derailed the thread with the boxing rant…
My son is three, and if he wants to play football when he gets older, I'm fine with that. I played tackle football from 4th grade through my senior year in high school, and I loved it, and have great memories of it. I played a bunch of other sports in school, but football was the only one I stuck with all the way. (I had no desire to play in college, and was definitely too small to play O-line at the D2 college I attended anyway). Football is fun. School age guys are aggressive, and the game is a great way to harness that in a constructive team setting.
I do think there's some merit to the argument that SOME parents aren't letting their kids play football now, but there were parents when I was in school 25-30 years ago that didn't let their kids play football either. That will always be the case. I do think that the point of sports specialization is really the key reason for any present or future decline in the game. I've often said that football is the last sport that resembles the era in which I was in school, where you played a sport for a season, and went on to the next season/sport. Pretty much every other sport (except maybe golf) has become a year-round deal for kids as young as grade school. With traveling teams, AAU, camps etc., kids are expected to dedicate their lives to one thing all year. When you have that level of specialization, there's no time away from it to play other sports, and football is going to be the one to suffer. When your peers on the wrestling/basketball/swimming/hockey teams are spending the fall preparing for their season, and you're playing football, what's going to happen to your spot on those teams come winter? You saw the start of it when I was in school, where the serious hockey/hoops players stopped playing football because of a slight overlap in the seasons and the risk of getting cut from the teams because they were still playing football. Personally I think it's sad, and a lot of kids are missing out on fun experiences because of this, but that's the world we live in, particularly in larger suburban districts.
Football may or may not be declining, but if it is, it's a far more compiex issue than Pat's simplistic column. (and I'm normally one of the few defenders of Reusse here - I think he's a good writer).
