The Dallas Cowboys will be a little more familiar with Robert Griffin III when they visit FedEx Field on Sunday night in a showdown for the NFC East title, but a second look at the rookie quarterback hasn’t given other opponents a significant edge this season.

Redskins offensive coordinator Kyle Shanahan said this week that neither the New York Giants nor the Philadelphia Eagles took a dramatically different approach on defense the second time around against Griffin.

“Neither of them were very drastic,” Shanahan said. “There are a couple subtle things they do with fronts and some of the techniques they play with their [defensive] linemen. But neither of them was a drastic change…. You’re always ready for something to be totally different than what you’ve seen on tape. So far this year, people have just tried to play pretty sound defense and make the tackles and not give up big plays.”

Griffin played well in his second game against both the Giants and Eagles, although in each case his numbers dropped from the first to second meeting.

He had a passer rating of 108.9 and ran for 89 yards in his first game against the Giants, then had a passer rating of 101.9 and ran for 72 yards in the rematch. He had a perfect passer rating of 158.3 and rushed for 84 yards in the Redskins’ first matchup of the season with the Eagles, then had a 102.4 rating and ran for four yards in the second meeting last Sunday.

“I think there’s always some schematic differences,” Shanahan said. “You get an idea from the first game how they want to play some stuff. So you know a little bit more what to practice and everything. Then you also have to be ready because they’re definitely going to have a better idea of what they want to do. They’re going to have some adjustments. I think it all evens out.”

The good news for the Redskins was that they won both rematches as part of their current six-game winning streak.
