Its just about PR. These kids in pee wee are not in that much risk. They are small. their pads make them look like Darth Helmet from Spaceballs and they usually just crash into each other and fall over moreso than real hard tackles.
My concern is that with all this teaching of moving your head while tackling, they will cause a rise in neck injuries.
if the NFL was really concerned about it, they would tweaking the passing rules. It's the favorable passing rules that have caused increased injuries.
when you run the ball, there are collisions but they are close collisions with neither player at full speed. With all the passing, you are seeing long range collisions with 2 players going full speed.
This stems from them not allowing DBs to touch WRs at all. This has led to many small WRs going over the middle becuse they are no longer restricted. Years ago, only TEs and big WRs went over the middle. Now you have tiny guys like Desean Jackson flying through the middle and meeting 250 Pound LBs.
Blame the offensive coaches for sending boys to do a man's job over the middle. Why is it always the defense that must adjust?
