I think it's important to note this:
stated that S.D. was running formations that Dallas had never seen. Norv Turner ran like 4 screens in the first half.
The Dallas defense, like the Dallas offense, was playing very vanilla.
showed his craftiness (he knew the out was coming and baited Rivers and jumped it) on that pick and his good ball skills. He may have picked the first one off, but I don't think the ball was thrown where he thought it would be. The WR had to jump high and catch it kind of behind him. Rivers went back to the out, and the ball was there on the second one.
didn't look great on that Spencer sack, he would have trouble playing over Marion Barber here.
