Early analysis from Invesco

DENVER -- The Cowboys attempted to establish the running game on their first possession -- with limited success. Marion Barber had a tough run for a first down, but that was the only thing the Cowboys accomplished. Tony Romo was blown up on the play the Broncos were called for defensive holding.

Then Elvis Dumervil got Romo for his seventh sack of the season. Early on, Dumervil's sort of free-lancing. Keep your eye on Broncos linebacker Robert Ayers. He made Flozell Adams look really, really bad on an inside move. Adams didn't even have time to get his foot out to trip Ayers.
