Why do I have to find these things for you? Here is one of them I found with a quick search.
What help could have been given to Chaz Green?
Broaddus: I asked (Cowboys head coach Jason Garrett) this question today, when you think about double-teaming, or helping, or chipping away, and all that... tackles don't usually like help on the outside because tight ends get in the way, running backs get in the way. They get out of position and it messes up your block, so you've got two guys screwing up the play instead of just one. He goes, "You're absolutely right about that. You want to help him as much as you can, but you have to be careful of how you help him."
He said, "Let me tell you this though, as a staff, we made a bad mistake. We should've got some help sooner, we should've tried some things sooner. That's on us."
