I disagree. What I see is a great comparison of videos showing the importance of quality offensive line play. The first video shows the D-line winning with the stunt, leaving Davis nowhere to go. The second video shows our o-line picking up the stunt, giving Cook room to operate.
Of course, from there, Cook worked serious magic, showing how dangerous he is. If he was the RB in the first video, he would have been stuffed, like Davis.
