The Dallas Cowboys’ problems running the ball begin with poor blocking.

That was the case last season when the Cowboys ranked second to last in the league in rushing offense setting a franchise record for futility. That was the case again last weekend in Kansas City when DeMarco Murray gained only 25 yards on 12 carries.

“They weren’t really moving anybody off the ball” former Eagles and Redskins pro personnel director Louis Riddick said during a Wednesday appearance on ESPN Dallas 103.3 FM’s Fitzsimmons and Durrett.

But Riddick an ESPN analyst now doesn’t believe Murray should avoid blame. That’s because he doesn’t see Murray avoid tacklers nearly often enough.

“DeMarco is a hard runner but I have always had some issues with DeMarco because he is very very very straight line” Riddick said. “He has no ability to make people miss.

“As a matter of fact you saw numerous times that there were some holes that DeMarco could have got through but he is a guy who has to gather himself to really make hard sharp cuts to exploit those running lanes. Sometimes it looks like he’s leaning so far forward he’s stumbling his head’s down and he’ll just run into the back of his own lineman run into holes where it’s obviously clogged up and he’s not able to move laterally.
