Del Rio was on a short leash heading into Thursday’s prime time matchup. A blowout loss to the Bears in Week 5, plus two losses to a three-win Giants team, which included a Week 11 loss to Tommy DeVito, left little hope of Del Rio sticking out the season. The Thanksgiving Day beat down against the Cowboys was simply the final straw. In what is sure to be one of several coaching changes in Washington over the next few months, Del Rio’s firing is the first domino to fall, as head coach Ron Rivera will now take over defensive play calling duties. The Commanders ranked as a top-10 unit in several defensive categories last season, but are now allowing the most points per game (29.2) and the fourth most yards per game (377.7). They’ve become the “get right” defense for every opposing quarterback and fantasy manager this season. While we’d expect that to continue, whatever happens from here on out will take place with Rivera calling the plays. In addition to Del Rio, the Commanders also fired defensive backs coach Brent Vieselmeyer.
