Thank you so much for sharing that!
As far as the first video, absolutely preach! Defensive players have absolutely been screwed at times for offensive mistakes, and that's probably the refs and rules biggest failures, and something I've been pissed at the Packers at times, in that, they don't take advantage of this... when refs are screwing the defenders, the Packers defense gets screwed and then Packers offense doesn't use the same tricks to get the refs calls.
The Ssecond video, Brady makes a good point, but to some degree doesn't that point counter the point he made in the first video? Just saying... but he's right, it should be all knees are protected or no knees protected. That being said... maybe it should be no knees (except linemen, a lot of dirty cheating can go on in the trenches if you don't protect their knees)... but some of the calls on the QBs knee have been down right awful. Like I think Nick Perry on Russell Wilson, he hit him on the hip, Wilson kept running and broke the tackle as Perry fell down and Wilson running out of room throw a bad pass, 4th down. Flag, illegal hit to the QBs knees.... 1st down.... what?!? That was to his hip and he fell down and failed to wrap up... that wasn't to the knee at all.
