Defense, particularly the DL, played better than expected.
Special Teams were "eh." Harris' muffed punt was uncharacteristic. But the holding penalty when SF had to re-kick wasn't.
OL played well. Murray ran well. Linehan (or Garrett), how do you not run 2nd 1 at the 2? Idiotic.
Romo was gawd awful. Terrible reads/decisions, that got Dez hammered to where he was having "hydration" problems the rest of the game. This when he had Williams over the top. Off on throws. Missed a wide open Beasley on a no less than a 20 yard gain and was 6 if he could have made one guy miss. Looked like a rookie that was totally unprepared for the speed of the NFL game. Or like someone that didn't practice/play the entire off-season.
Succinct enough for you?
What does it mean for the rest of the season? Ask me after the 4th game.
