While there will be plenty of speculation over the future of a certain head coach during Sunday's game, which could be his last with the team, the same could be said on the opposing sideline as well.
Ironically enough, Redskins head coach Bill Callahan, who was named interim coach earlier this year when the team fired Jay Gruden, is rather familiar with the home side as well.
Callahan was the offensive line coach and running game coordinator for three years under Jason Garrett from 2012-14.
While Garrett is the final year of his contract and could be coaching his last game with the team, Callahan's future is also up in the air as the Redskins are just 3-12 entering the final game of the season.
Callahan and his team likely won't be scoreboard watching, albeit for possible draft positioning. Meanwhile, the Cowboys will have an interest in the Eagles-Giants game that will be playing at the same time in New York. A Giants win, coupled with the Cowboys beating Washington would give Dallas the NFC East title and a spot in the playoffs.
On Tuesday, Callahan spoke to reporters from the Dallas-Fort Worth media in a scheduled conference call. He spoke about not only his time under Jason Garrett, who was just in his second full season as head coach when Callahan joined the staff.
"I have a lot of respect for Jason," Callahan said. "I think he was tremendously well-organized. He was a really good communicator with the players.his messages were always spot-on with the opponents we were playing. He was very demanding as a staff member as to what he wanted. He demanded precision."
Callahan also had a front-row seat when the Cowboys were building this offensive line. He coached Tyron Smith in his second year and was on the staff that drafted both Travis Frederick and Zack Martin. And he still gets to keep tabs on those guys, even when he's just watching film for his own team.
"There's so much crossover film within the division so i get to eyeball those guys a lot with the common opponents that we're playing," Callahan said. "We see their film and what they're featuring. I've continually watched them grow and mature and excel at their positions. I'm glad for Travis that he's having a good year. I was concerned when he got ill and he overcame his obstacles. I've had a lot of lines in that time, but that line itself was one of the hardest working groups that I've ever been around."
