With our legs and knees there is enough bad stuff that can happen on accident. But to allow someone to intentionally take a shot on someone's knees? That's kind of rough. I don't want to say this is how it should or shouldn't be, but this is how we take care of our families. It's not like they are blocking like that to hurt anybody, but once you are hit below the knees anything can happen. I'd like to see (the offensive linemen) stay on their feet.
