Tony Romo concentrated too much on getting the ball to Terrell Owens; and then missed a wide open Sam Hurd for a touchdown.
Marion Barber didn't provide a spark in the running game, as was promised, and was a non-factor during the time that the first stringers were playing except for one nice play on a dump pass. Felix Jones is already showing more pizazz than Barber.
The real issue, though, is the lack of definition on the part of the offense when it comes to continuity.
What I mean is, that they seemingly are over confident in the passing game, and are trying too many lower percentage- big yardage plays; which result in 4th downs when the defense is able to stop them.
It reminds me of an Ernie Zampesie offense. He always said he had to make himself call a running play.
The Cowboys cannot expect to 'wing it' all year long on the arm of Tony Romo. It will take a consistent running game that will chew up the clock, and demoralize and wear down the defense; and that is when the offense can expect the big plays from the passing game.
There's one glaring problem that's hanging over from last season- the lack of committment to the run, giving continuity and rhythm to the offense.
The overconfidence of the offense is scary at times- but they are not doing what it takes to be dominant on the field. Anybody can throw the ball.
It takes a champion to drive the field with control and direction- wearing down and demoralizing the other team's defense with physical power, and then striking quickly with the pass when the opportunity is there.
