You seem to have the same focus problem as other posters here. The game of football is just a game, and has some of the same virtues as most any other game. The commercial spectacle of football, with the accompanying cheerleader tittilation, enhancement drugs (your laughable defense to the contrary notwithstanding), mob gambling involvement, and ruthless partisanship with megabucks on the line, however, is a far cry from a game, and undifferentiable from JJ and Timberlake's shenanigans in terms of suitability for viewing by the young--save that, to the unprejudiced viewer, it's far scarier, on a far larger scale, such as to put one in mind of the roman circus.
You are way oversimplifying the game of football to necessarily be filled with "dumb jocks" or other athletic stereotypes.
Hey, I'd be ecstatic if it were just a matter of "dumb jocks". I like dumb jocks--I am one. Marginal scholars and high school and college dropouts making millions of dollars for bruising and bashing other human beings, while some of the prettiest woman my kids will maybe ever see chant and cheer themselves into undulating half-dressed ecstacy over it, however, is not an aspiration I want pounded into my kid's psyche every saturday afternoon. I'd rather go back to cartoon violence. Less real looking, and therefore, less likely to be subconsciously pursuasive.
While there are cheerleaders at NFL games, they are hardly the centerpiece or even a fraction of the broadcast. You typically only see them at the TV breaks and the advertisers logo are usually on the screen, so you can see them anyway.
The other issues that you noted --drugs, gambling, partisanship-- no child would see that. That isn't something that you can see during the broadcast; and if it is, it is very subtle.
To be fair, as an adult and someone who has read a great deal about and experienced some of the "under belly" of the sports world, I have to admit that I am aware that this is going on (and in probably too many clubhouses that I would be comfortable admitting). But again, kids can't see this side of the game from a television broadcast.
So, I think saying that a kid can get all of this out of the broadcast is a bit much, though, again, I won't deny that some of the aspects of professional sports is a joke.
We can agree to disagree.
