Quarterback Robert Griffin III put the progress of his rehabilitation from knee surgery on display Thursday at Redskins Park, running and throwing on the side while his Washington Redskins teammates went through an offseason practice. Griffin said afterward that his surgically repaired right knee “feels great,” and that he hopes to be ready to participate in training camp and open the season in the team’s lineup. He brushed off any notion that his relationship with the organization is in need of mending by saying that he and Coach Mike Shanahan had “hashed everything out” about the handling of Griffin’s injury. “There was an unfortunate situation there at the end of the season,” Griffin said. “I don’t think there’s anything that needs to be repaired. Obviously we all just need to move forward and continue to just let that bad taste that was in everybody’s mouth just get out, and move forward to the next year. “The only thing that needed a repair from last year was my knee. And that is repaired, and I’m ready to go.” Griffin did not participate in Thursday’s workout but was on the field. He dropped back and threw passes to wide receiver Pierre Garcon, tight end Fred Davis and other players also rehabilitating from injuries and not participating in the drills. Griffin’s throws were relatively crisp. He appeared to be able to plant on his right leg and deliver passes, although he and his receivers were moving at far from full speed. Griffin also did some running near the beginning of the practice. “The knee feels great,” Griffin said later at a news conference. “I’m able to do all the stuff out there without any hesitation. So that’s the best part about it. I’m excited about that. It’s all about having that confidence. If you put the work in, you’ll have that confidence when you get back out there on the field. It’s about playing like you were never injured.”
