First off, you quoted my post but changed it to fit your narrative. I never said a chop block was legal. Yes the film doesn't lie, I even said you all was correct on the play against #71 was a chop block. Whether it was intentional or not is a matter of opinion and no one knows the answer to that so speculate all you want. The other blocks toward the knees you refer to are called cut blocks, in case you didn't know, and are legal.
