The Washington Commanders are putting their long-standing label of laughingstocks behind them with their winningest season since the 1991 campaign.That season also marks the franchise’s most recent Super Bowl title. The current squad clinched a playoff berth last weekend and looks to finish the regular season in style when it faces the Dallas Cowboys at Arlington, Texas.The Commanders (11-5) are seeking their fifth straight win. A victory would mark just the fourth time in franchise history that Washington has won 12 or more games in a season.The Commanders also can clinch the No. 6 seed in the NFC with a victory, giving them something for which to play as the NFC seeding sorts itself out.The last team to beat Washington is the Cowboys, who delivered a 34-26 win over the host Commanders in Week 12.That began a stretch in which Dallas (7-9) won four of five games before it was walloped 41-7 by the host Philadelphia Eagles last weekend.What remains to be seen is whether or not this is Mike McCarthy’s final game as the head coach of the Cowboys. McCarthy’s contract is about to conclude.Dallas owner Jerry Jones spoke favorably of McCarthy this week but the coach sidestepped a question pertaining to his future.”I need to make sure I’m doing exactly what I’m asking everyone else to do. We need to finish the race,” McCarthy said in reference to the season finale. “It’s been a challenging year, based on our contract situation for coaches. It’s stating the obvious, but we’ll have time to talk about that next week.”McCarthy is 49-34 in five seasons with the Cowboys. His teams were 12-5 and made the playoffs in each of the three previous season.But quarterback Dak Prescott sustained a season-ending hamstring injury during the team’s eighth game of this season. When McCarthy went 6-10 in 2020, Prescott was lost after five games of that season due to his horrific ankle injury.Cooper Rush is 4-4 as the Dallas starter this season but there is no guarantee he will start Sunday. McCarthy said he’s also considering Trey Lance (seven passing attempts this season) and Will Grier (zero attempts). The latter was signed to the practice squad in mid-November.”The reality of it is, we’re going to work all the guys,” McCarthy said of the quarterbacks.Washington has no issues at quarterback with rookie Jayden Daniels exceeding all expectations. He was named to his first Pro Bowl team on Thursday.
