Here is what you need to know on this Sunday, December 20, the day the Washington Redskins host the Buffalo Bills.

Five final thoughts on Redskins vs. Bills

—Two Bills who were questionable on the final injury report, RB Karlos Williams (shoulder) and DE Mario Williams (illness), are both expected to play. Karlos, who has missed the last two games, provides some quality backup to LeSean McCoy with an average of 5.7 yards per carry. Mario was a first-team All-Pro last year with 14.5 sacks but he has just four in 12 games this year.

—The Bills give up an average of 104 yards per game rushing. I think if they were honest the Redskins would sign up for that right now. Sure, they would like 150 yards or more with either Matt Jones or Alfred Morris carrying the load and going over 100. But it’s too much to expect things to click in the running game all of a sudden. If Kirk Cousins is generally as efficient as he has been at home lately around 100 yards should be enough.

—One area where the Redskins have a solid advantage over the Bills is at tight end. Jordan Reed is coming off of one of his best games of the seasons with nine targets, nine receptions for 120 yards and a touchdown against the Bears. He will go up against a Bills defense that is 11th in the league in fantasy points given up to tight ends. The Bills will be without starting tight end Charles Clay (51 rec., 571 yards, 3 TD), who is sidelined with a back injury. Chris Gragg, who has 9 receptions for 115 yards, will play in his place.

—The Bills have lost three of their last four games. In those three losses they have turned the ball over a total of five times. They had no turnovers in five of their six wins this year. You don’t have to have an advanced degree in football analytics to see what the Redskins will have to do to win this one.

—I’ve been going back and forth all week on this one. The Redskins are playing well at home but they did lay an egg against Dallas the last time they were there. It’s reasonable to expect Cousins to have a good day against a Bills pass defense that can’t get pressure and is in the middle of the road. Tyrod Taylor also should be able to throw the ball and Sammy Watkins is a dangerous weapon. I think it will come down to the Redskins’ ability to stop the run. They have allowed less than 100 yards rushing in each of their last three games. If they can do that against McCoy, Karlos Williams, and the scrambling Taylor they should come out with a hard-fought win. If they go off for a buck fifty on the ground, the home team will be in trouble.
