I saw what Breer saw when he watched Wilhite on tape. The Texans were picking on him all day.
OTOH, when Breer blamed Koppen for Mario Williams' sack, I thought it was Mankins' fault. He kept blocking the DT, but probably should have disengaged and picked up Williams as he was stunting. Both Mankins and the LT blocked the DT, and no one blocked the DE.
