All season long, Washington Redskins coach Mike Shanahan and offensive coordinator Kyle Shanahan have talked about their desire – and need – for a balanced attack that features a blend of the pass and run.

But Sunday saw another week of Redskins’ offensive struggles..

The unit hit rock bottom, failing to score a point and producing only 178 yards – the lowest output since 2007. And as was the case in many of the previous weeks this season, the offense was anything but balanced. Unofficially, Kyle Shanahan called 45 pass plays and nine rushing plays. Another three rushes came when John Beck took off scrambling on broken plays.

The Redskins generated only 26 rushing yards and 208 passing yards, and the team lost 56 yards as a result of nine sacks.

Despite the ineffective attack, Shanahan said the offense struggles haven’t come as a result of poor scheme or play selection. Shanahan said he is “pretty comfortable” with the offensive playcalling, and said, “I’m heavily involved with the offense.”

A week after Shanahan primarily blamed a loss to the Carolina Panthers on an unprepared defense, which gave up 407 yards to Cam Newton and his teammates, the coach was asked if the offense was properly prepared to face a demoralizing Bills defense.

Initially, the coach brushed off the question, saying, “What we do today is you go back, especially when you have a goose-egg up on the board, you go back and you look at the things – you might miss an assignment, you might miss a block – you go through all of those things one at a time and collectively you try to improve.”

Later, he said the offense’s struggles could be traced primarily to the fact that the unit was without five starters, has been forced to replace those starters with unproven players and has a new quarterback in John Beck, who is playing for the first time since 2007.

“Any time you add a new center, a new left guard, a new left tackle, you’re using two tight ends not as much, you’ve got a couple of [new] wide receivers in there, it’s not going to happen right away,” Shanahan said. “It takes some time for those guys to work together. Some games will be better than others. All you’ve got to do is keep on working, try to get that chemistry to gel, and hopefully it will gel.”
