Washington Redskins quarterback Robert Griffin III knows what propelled him to success as a rookie in the NFL. He understands what has been missing early in a disappointing 2013 season. Now it’s time to get back to it. Griffin ran for 77 yards against the Dallas Cowboys on Sunday night. It was more than his combined yardage through the first four weeks of the season (72). Expect to see more of that starting this Sunday against the Chicago Bears as the quarterback continues to progress from last January’s knee surgery. After a cautious preseason in which Griffin was kept out of game action and then ran far fewer of the read-option plays that fueled Washington’s offense last season there were signs of a breakthrough in the Dallas game. But they weren’t necessarily obvious in a 31-16 loss in which the offense again struggled to punch home its chances inside the 20. “Everybody wants me to slide and get out of bounds and do that whole thing” Griffin said Wednesday during his weekly press conference at Redskins Park. “For me I can’t really listen to that. It’s not that you ignore it. I understand that people are concerned. But at the end of the day you have to go out there and play with your instincts.”
