''I would be lying if I said I'm not going to pay attention to it,'' the Pro Bowler said Wednesday. ''Me, I'm thinking about the possibilities in my head all the time.''
Washington (8-7) plays Dallas (4-11) in Week 17 after clinching the NFC East and the conference's fourth seed with a Week 16 victory over Philadelphia. Other results will determine whether Green Bay, Minnesota or Seattle travels to FedEx Field for a wild-card game the following weekend. The Seahawks beat the Redskins in a 2012 wild-card game, Washington's last postseason appearance.
With only bragging rights at stake, veterans such as Williams and others could be rested, giving this week's preparations an unfamiliar feel.
''I ain't never had that,'' said Williams, who didn't participate in Wednesday's practice because of minor knee and foot injuries. ''This is uncharted waters to me. If he lets me rest, then I'm going to rest. But if he needs me to go out there and play, then I have no problem doing that.''
Coach Jay Gruden suggested that fully healthy regulars will play Sunday, and that his staff is still determining exactly how to approach the game.
''There are a couple different ways to look at this,'' Gruden said. ''It's important for us to be healthy come playoff time, but it is also to have some kind of momentum also going in.''
The Redskins have won three straight for the first time since taking seven in a row in 2012. And quarterback Kirk Cousins said he'd like to keep building his momentum after throwing for more than 300 yards and four touchdowns in consecutive games.
''I feel good and I want to play, and I feel as a young player that I want to continue to develop and get a rhythm,'' said Cousins, in his first full year as a starter. ''I'll always defer to the head coach with whatever he decides. I think it's a pretty fluid situation.''
Williams, however, rejected the idea that resting players could hurt Washington's playoff prospects.
''We're all professionals, we're all grown men,'' He said. ''I don't believe in the whole getting rusty thing. I think it's a cop-out answer for people whose plan didn't work out as they thought it would.''
NOTES: Gruden said he hopes LB Perry Riley (foot surgery) could see action Sunday. He last played on Nov. 29 against the New York Giants. ''I'd love to get him out there - at least pre-game warmup, let him run around, maybe get a series or two,'' Gruden said. . DE Jason Hatcher (knee, neck), DB DeAngelo Hall (calf), CB Quinton Dunbar (quad) and S Dashon Goldson (shoulder, rib) were also held out Wednesday.
