…Quarterback Robert Griffin III is working out six or seven hours a day, coach Mike Shanahan said, and remains ahead of schedule in his return from knee surgery. But Shanahan is taking a cautious approach.

Griffin had his right ACL reconstructed and had the LCL and MCL repaired two months ago. Shanahan said that head athletic trainer Larry Hess told him Griffin’s muscles are “stronger than he anticipated.”

“He’s doing everything he can to be ready for this season,” Shanahan said of Griffin. “Is he going to be ready? I have no idea. I’m sure keeping my

fingers crossed. And if work has anything to do with it, he probably will. But I’ll be able to tell you more about that in July.”

…Unrestricted free agent tight end Fred Davis is still working out at Redskins Park. The Redskins would like to re-sign him, but considering their cap situation they’ll have to release a player, or two, or re-work contracts. Because of his Achilles injury, it could be that Davis takes time to sign after gauging his market value.

“He’s working out extremely hard, doing everything we were hoping he would be able to do at this time,” Shanahan said. “He’s not ready yet, but he will be ready for this season. I don’t think there will be any setbacks. I have not gotten a chance to see Fred run, but you can tell he’s in great shape.”

…Linebackers Brian Orakpo and Keenan Robinson, both recovering from torn pectoral muscles, are working out together in Austin, Texas. Shanahan said Orakpo feels “very good” and that Robinson should be back here ready to work out in April barring a setback.

…They restructured defensive end Adam Carriker’s contract. According to CBS Sports, Carriker turned $1.4 million of his $4 million salary into likely-to-be-earned incentives. They guaranteed $2 million of his salary. Had they released Carriker they would have saved a little more than $2 million in cap space. But there was incentive for Carriker, coming off a season-ending knee injury, to agree to such a move.

…The Redskins don’t have to make another move to get in compliance with the salary cap, but they will have to do so if they want to sign anyone, whether it’s a release or restructuring. That means in order to re-sign linebacker Lorenzo Alexander they’d have to either restructure another contract or cut a player.  One source said the talks had been productive, but there was no deal as of Monday night. Alexander had rejected an earlier offer.

“You always want to sign your players, and Lorenzo has been a big part of this organization,” Shanahan said. “I hope we can compete with people financially. But at the same time, he’s got to do what’s best for him and his family. We’ll find out and see if we’re in the ballpark, and hopefully we are.”

…Receiver Santana Moss remains on the roster. There were reports that they were discussing a contract restructuring. But the Redskins are loath to add future years to deals and Moss is entering his final season. It could end up looking more like a pay cut with incentives. If Moss were cut, the Redskins would create approximately $4 million in cap space.

“If you’re going to restructure a guy’s contract you’re hoping that guy will be on your team for a length of time,” Shanahan said.

At 34, it’s debatable how long Moss will be around in Washington even if he returns this season. That’s why a cut with incentives could be the option.

..Washington also signed offensive tackle Tony Pashos to a one-year contract. Pashos did not play last season while recovering from ruptured tendon in his right foot. He missed 10 games in 2010 because of an ankle injury. It’s hard to imagine him being more than a backup in Washington, unless the Redskins can’t afford anyone else. They have remained in talks with last year’s starter, Tyler Polumbus, but there was little movement on a deal.

…A league source said the Redskins have had very casual conversations with free agent corner Sean Smith. He’ll be in demand on the open market and likely unaffordable for Washington. They’ve also shown interest in other corners: Greg Toler, Antoine Cason and Derek Cox and could make a run at Kyle Arrington. USA Today reported that they could make a push for Aqib Talib, who has ties to general manager Bruce Allen and secondary coach Raheem Morris. But the Patriots apparently want him back. The Redskins lack the cap room and if Talib is too expensive they would have to make some tough decisions. Like every other corner on the market, Talib has his flaws.

…Shanahan made it clear that the Redskins would not ask linebacker London Fletcher, who will make $5.5 million this season, to take a pay cut. A team source had said the same thing two weeks ago. As for Fletcher’s announcement that he plans to return, Shanahan said, “He’s full speed ahead. When that guy is full speed ahead, he normally plays at a very high level. I’m excited that he’s doing whatever he can to get himself ready. When he says he’s going to get himself ready, he’ll be ready. So I’m looking forward to him leading our football team on defense and doing the things he’s done since he’s been here.”
