I think you're probably right. As technologically challenged as I am, I must admit I dial my cell phone frequently why driving down the road. This coach didn't do anything the rest of us don't do. Did he use poor judgement? No doubt. Will he do it again? Highly unlikely.
My guess is the kid who filmed this doesn't get much playing time and took this opportunity to get even for his lack of talent.
The mother or father who went to the news and thought they would get the coach fired only put more credibility to this kid's immature behavior. Perhaps if mommmy and daddy worried more about what the boy did in the classroom than what he does on the soccer field, they might get it.
Until then this is just more media hype. Anyone under 50 who says they have never texted while driving and probably when they have kids in the car are probably full of BS.
