I don't think it was strange at all. They were consistently wrong in favor of Washington. It got so bad that in the third or fourth quarter (after Bo's challenge, if I recall correctly) there was a play where Burkhead ran the ball close to the marker, and you clearly see him get up, look at the head line judge (the guy on the Washington sideline), then turn around and jog toward the middle of the field to toss the ball to the lineman, even though the head line judge was standing almost right next to him. The players knew they were getting robbed by that guy. Bo challenged that spot just to let them know he was onto them.
