Washington Redskins Offensive Coordinator Kyle Shanahan says his playcalling will not change because of the switch from Rex Grossman to John Beck as starting quarterback.

During two fourth-quarter possessions Sunday, Shanahan went to the bootleg several times, taking advantage of Beck’s mobility. But Shanahan said that overall, not much changes with the Redskins’ schemes, and he won’t need to lighten Beck’s load by scaling back on pass plays.

“I’m confident in both of our quarterbacks, I like both of our quarterbacks and think we can win with both of them,” he said. “I think they’re similar. There are obviously some things one guy does better than the other and vice versa … but I don’t change.”

“You always want to put guys in the situation to make them most successful,” Shanahan added. “I think there are things that both guys do well. … It always changes a little...based on game-planning. But everything’s built into the offense. You don’t have to make the change from week to week. We didn’t have to make a big change in the fourth quarter when we put him in, we just expected that he could make the plays when he was in.”

Beck tucked the ball and ran twice – once on a bootleg when no one was open (he gained 12 yards) and once on a two-yard draw for a touchdown. Shanahan acknowledged that Beck is faster than Grossman, but said he didn’t expect to add more quarterback keepers into the gameplan because of that.

“He can do a little bit more with his legs, but I know that he’s definitely not faster than the guys out there on the defense,” the coach said.

Immediately after Grossman’s fourth interception against the Eagles, Shanahan told Beck that he would be taking over at quarterback during that game. But he said that Coach Mike Shanahan was the one who made the decision on which quarterback would be the starter in the future.

“It operates here just like it does anywhere else,” Kyle Shanahan said. “I’m the offensive coordinator, so he obviously asks my opinion. . . But when it comes down to it, it’s his decision.”

This week Beck has worked on regaining the chemistry and timing he had with his receivers during the preseason, but his feel for the playbook remains solid, Shanahan said.

“He’s done a good job. It’s his first time really getting reps with the first team since training camp,” Shanahan said. “But he’s doing a good job and we’ll get him better each day and ready for Sunday.”
