Robert Griffin III has said that he is not under pressure to match his 2012 form with the Washington Redskins.

The quarterback, who was named the league's offensive rookie of the season last year, spent the off-season recovering from knee ligament surgery.

The 23-year-old told reporters: "I think the league does evolve, but at the same time, I have to be that guy. There's no pressure, none whatsoever. You've still got to go out and play football, and that's what I was talking about after the game. just getting back to being me.

"You know how to play the game. Listen to your coaches, go through that whole thing and just go out there and play and have fun, and that's what it's about.

"So it's not that there's pressure to be a certain guy or have a certain amount of numbers, I could care less about the numbers as long as we win. If we win games, all is good."

The Redskins, who are third in the NFC East with just one win so far this season, face the Chicago Bears on Sunday.
