Mike Shanahan has said that the Dallas Cowboys try to keep their opponents off balance.
The NFC East side, who sit at the top of their division with a 2-3 record, host the Washington Redskins tomorrow.
The Redskins head coach told reporters: "They do so many things. They go slot. They go base. They'll go different personnel groups. Like most NFL teams, they'll try to keep you off balance. They'll try to get matchups or mismatches working up your personnel.
"They'll change it up. I think that was happening [in] the last couple of games, [with] what they've been able to do throwing the football. Like anything, they have a philosophy and they stick with it.
"What they have done through the years is play well and play very solidly, and you've got to really play well. All 11 guys have to play together."
The Redskins beat the Cowboys in both of their games against their divisional rivals last season.
