It's bad enough that the moms' clinic in Chicago last month never touched the topic of how many kids are killed or broken playing football every year. And worse that it included a demonstration of what's called "Heads-Up" tackling, a technique that claims to teach kids and coaches how to avoid head and neck injuries 鈥?as if such a thing were practical in real games,Andy Lee Jersey, instead of practically impossible.
