Robert Griffin III tried to sidestep the question in the same way he evades defensive linemen. The Redskins quarterback engineered Sunday's 27-20 win over the Eagles at Lincoln Financial Field, basically playing on one leg.

After a 38-21 loss to the Cleveland Browns last week with a knee injury, a mild sprain to his right lateral collateral ligament, Griffin completed 16 of 24 passes for 198 yards, two touchdowns, and one interception. He had a 102.4 passer rating.

But Griffin did not run much, with just two carries for 4 yards. He has rushed for 752 yards and six touchdowns this season, so it's a big part of the rookie's game.

He said his knee felt good, but when he was asked if he had any limitations, Griffin skirted the issue.

"I mean, we won the game," said Griffin, who was sacked once for 13 yards. "I was playing quarterback for the Washington Redskins, so I felt like myself out there."

Even Redskins coach Mike Shanahan wasn't buying that explanation.

"We did not do everything that we would normally do," Shanahan said when asked on the running limitations for his quarterback. "I did not want to put that pressure on that [knee]."

Even without Griffin as a running threat, the Redskins rushed for 128 yards. Rookie Alfred Morris led the way with 91 yards on 22 carries.

A year after winning the Heisman Trophy at Baylor, Griffin has led the Redskins (9-6) to six straight wins and a chance to clinch the NFC East title Sunday at home against the Cowboys.

Even on a day when he wasn't a running threat, Griffin was still good enough to beat the Eagles.

"They call me a quarterback because I lead the team," said Griffin who has thrown 20 touchdown passes and just five interceptions. "I'm supposed to go out there and throw the ball and hand the ball off to Alfred [Morris], and that's what I was able to do."
