On that key 3rd down where Schaub went down like a fainting goat, he did have a legitimate reason for his head and neck to be in pain. After Schaub goes down, Roman Harper goes down to cover up Schaub. The video is here: http://www.nfl.com/videos/new-orleans-saints/09000d5d82291002/Saints-defense-sack-6-yd-loss From the last two slow-mo angles, it looks like Harper intentionally raises his right knee/thigh to plant it onto Schaub's dome. Very sneaky cheap shot there by Harper. Judge for yourselves. I think it looks fishy. Why raise his right leg off the ground like that? It looks unnatural, unless you were intentionally trying to knee the guy in the head. edit: gifs for those that don't want to click the link watch Harper's right knee and how he turns his hips.
