ASHBURN, Va. -- Robert Griffin III said Thursday that his goal remains to play Week 1, but he's not going to rush back at the risk of his career.

"That's always been the goal, but once again I'm not gonna risk my career to play in one game. Yes, I'm all in for Week 1 but I'm all in for my career as well," the Washington Redskins quarterback said.

Griffin held his first in-depth news conference Thursday since his reconstructive knee surgery in January. He also took part in an offseason practice session in which he wore a large black brace and ran drills with other teammates recovering from injuries.

He said he hopes to be cleared for training camp. Coach Mike Shanahan said that remains the team's hope as well.

The Redskins keep saying he's "ahead of schedule," but it's too early to gauge how much he'll be able to practice when training camp begins in late July.

"I really don't know what `ahead of schedule' means, except for the doctors, they keep saying he's ahead of schedule," Shanahan said. "We want to be patient with it."

Griffin, who said his knee "feels great," said he'd be comfortable playing Week 1 without playing in the preseason if the Redskins choose to hold him out until the regular season begins.

Griffin said he's "hashed things out" with Shanahan, who was widely criticized for leaving Griffin in the game after the quarterback was injured during the playoff loss to the Seattle Seahawks.

"We hashed everything out, we talked and we're moving forward from it. We talked about it, we're on the same page and we're ready to go win," he said.

Shanahan said the conversation was part of an overall review of the season.

"You talk about things that you could have done differently," the coach said. "Things that went poorly during the season, things that went well."

Griffin said he hopes to play smarter in 2013 so he can stay on the field for the Redskins.

"I can't change my mindset but I can be smarter about what I do out there," he said. "I've got a year of experience, which some might not think is a lot. But a year of experience in the NFL is big for anyone. I know what I have to do and what I don't have to do. It's about limiting those hits, making sure I'm staying out there for my teammates."
