The Redskins like that Robert Griffin III remains ahead of schedule. They just want to make sure he stays that way — and they’ll do so by making sure he’s not going too fast.

In January, Griffin underwent ACL reconstructive surgery and also had his LCL and MCL repaired in his right knee. Griffin is participating in the Redskins’ offseason workouts, which began last week.

“One thing I don’t want to do is see anything go too quick,” Redskins coach Mike Shanahan said. “Mother nature will take its course. That takes time. The thing I love about Robert is that he works the muscles around it and he loves to work and he does everything you ask him to do and then some to get himself ready. But there is a time frame and the ligament takes time to heal. We have to make sure he doesn’t go too quick. We don’t want himt o do anything too quickly because then he can set it back.”

Shanahan also said that as he gets to know players better, and they get to know him more, it helps in knowing when to pull a guy. Griffin consistently told the coaches and trainers he was OK and the medical staff cleared him.

“The thing we’ll make sure of is that Robert never plays if he’s not 100 percent,” Shanahan said. “If he tells me something I won’t believe him this year compared to last year.”

Shanahan then said he was joking about that last sentence.

“I think,” he added.

Shanahan, trainers and Dr. James Andrews all have talked about how well Griffin’s recovery is going. If all goes well this summer Griffin’s original timetable — six to eight months — would allow him to be ready for the Sept. 9 opener vs. Philadelphia.

But they will continue to monitor Griffin closely to make sure he’s not doing too much. That’s why Shanahan said he doesn’t want to get excited about what Griffin is doing.
