Will the offensive line sink the Cowboys in 2010?

I think there is no way to sugarcoat it at this point.  The Cowboys offensive line performance has so far reminded me a lot of the Washington Redskin's O-line woes from last season, when Jason Campbell and the running game had essentially no chance because no one could block up front.  All you had to do to defeat their offense was to bring the pressure, making sure not to open up any quick trapping running lanes in the process.  Campbell spent far too much time on the turf, and runners went no where or backwards much of the time. 

I'm really starting to wonder if Football Outsiders may be right.  The over-under for the Cowboys win totals for the year might be 7.5 wins.  Because without an offensive line pass and run-blocking effectively, it's gonna be ugly.  Cowboys play plenty of teams that can bring the heat.  And if that's the book on beating us, they'll bring it more and more. 

Last year, that didn't work that effectively.  Our line both pass and run blocked very well.  So how could it go down hill so fast?  It's a good question.  But last night, it wasn't just a factor of too many guys rushing to pick everyone up.  A lot of the guys who got through WERE BLOCKED.  Or only sort-of blocked.  And it wasn't just Barron and Holland being abused.  It was Gurode and Bigg and everyone up and down the line. 

Maybe the guys are just tired.  Too many preseason games.  No breaks.  Moving from San Antonio to Oxnard with road pre-season games in between.  Kosier and Colombo hurt.  Things can snowball. 

I'll just say this.  If the line doesn't show DRAMATIC improvement over what they've shown the last few weeks, the Cowboys aren't going to win the Division or even make the playoffs.  We don't have enough patsy opponents this year to get by on weaker line play than we've had the last several years. 

P.S.  I could write another post on the defensive side of the ball, which has been pushed around by power running attacks the last two weeks, and last night looked like it had huge gaps in the secondary, especially on underneath throws.   But while I think the defense will look better when it starts scheming, the O-line needs to show that it can block people, and so far it hasn't been able to.
