re: Have receivers' and QBs' injuries changed?

That was the initial argument. The passion to prevent head injuries would result in far more career ending knee injuries.

Seattle adopted this style of tackling years ago, the wrap up and roll causing stress on the knees...basically death roll Alligator-style. Prolonged pressure.

The upper-body and head is so off limits, you either wrap and tweak the lower body...or get crap like this...
