Dennis Allen: 'Struggles not all down to Matt Schaub'

Oakland Raiders head coach Dennis Allen has insisted that his side's struggles in pre-season are not all down to quarterback Matt Schaub.

The veteran signal caller has shown a lack of form during his side's matches as he completed just 13 of 27 passes against the Green Bay Packers and also lost a fumble during the defeat at Lambeau Field.

"We've got to improve ourselves as a passing game, and that's a full-team effort," Allen told reporters. "That's not about one individual."

The Raiders face the New York Jets in their regular-season opener on September 7.
