OU simply overloaded the line. They play mostly man coverage against our receivers due to wind. They also knew of our weak line and how putting pressure on Taylor was the key to stopping our offense (run game is void due to poor OL blocking). It seemed that they alsways had an extra man charging Taylor. The crazy thing is, the OU Dbacks are the weekest part of their defense, but they had no reservations about playing man. So IMO, are problems were 2 parts player difficulties (OL and QB), 1 part player mistakes (missed blocking assignments), and 3 parts formation and coaching problems (not allowing someone for the extra line personel) .
Murtha did much better than Thomas. Did he have a false start? Thomas is usually guaranteed at least 2 per game, in third and short situations.
