Going into Week 16 of the NFL schedule, the Pittsburgh Steelers are both struggling and secure.The Steelers have lost three games in a row after starting the season 11-0. The first two losses were understandable -- dropping one to Washington on an unplanned quick schedule turnaround due to COVID-19, and dropping one to a Buffalo Bills team that is simply very good. The third loss was inexcusable; the Steelers fell on "Monday Night Football" to a Cincinnati Bengals team that is one of the worst in the NFL and was relying on backups at quarterback and running back.At the same time, the Steelers aren't desperate. They've already clinched a playoff berth. While winning their last two games would give them a shot at the No. 1 seed in the AFC and a first-round bye, Pittsburgh at least knows they are securely in the postseason.In Week 16, the Steelers get another tough test when they face the Indianapolis Colts. Boasting one of the best defenses in the NFL, the Colts are 10-4 and still battling for their playoff spot. If the playoffs started today, Indianapolis would be the No. 6 seed in the AFC. But they've got a chance to clinch a top-four seed and a first-round home game if they can beat out the 10-4 Tennessee Titans for the AFC South division title.The Steelers and Colts kick off at 1 p.m. EST Sunday on CBS.NFL Week 16 Coverage MapsNFL Week 16 coverage map: CBSNFL Week 16 coverage map: FOX early gamesNFL Week 16 coverage map: FOX late gamesNFL Week 16: National TV gamesNFL Week 16 TV Schedule and ChannelsFriday, Dec. 25FOX, NFL NetworkMinnesota Vikings at New Orleans Saints, 4:30 p.m. ESTSaturday, Dec. 26NFL NetworkTampa Bay Buccaneers at Detroit Lions, 1 p.m. ESTMiami Dolphins at Las Vegas Raiders, 8:15 p.m. ESTPrime VideoSan Francisco 49ers at Arizona Cardinals, 4:30 p.m. ESTKyle Shanahan provided updates on all 4 quarterbacks on the #49ers roster + the two options for an emergency QB.📰: https://t.co/S9PygKuC22 pic.twitter.com/PhIhfVh7vT— San Francisco 49ers (@49ers) December 22, 2020Sunday, Dec. 27FOXAtlanta Falcons at Kansas City Chiefs, 1 p.m. ESTNew York Giants at Baltimore Ravens, 1 p.m. ESTCincinnati Bengals at Houston Texans, 1 p.m. ESTPhiladelphia Eagles at Dallas Cowboys, 4:25 p.m. ESTLos Angeles Rams at Seattle Seahawks, 4:25 p.m. ESTCBSCleveland Browns at New York Jets, 1 p.m. ESTIndianapolis Colts at Pittsburgh Steelers, 1 p.m. ESTChicago Bears at Jacksonville Jaguars, 1 p.m. ESTDenver Broncos at Los Angeles Chargers, 4:05 p.m. ESTCarolina Panthers at Washington, 1 p.m. ESTNBCTennessee Titans at Green Bay Packers, 8:20 p.m. ESTMonday Dec. 28ESPNBuffalo Bills at New England Patriots, 8:15 p.m. ESTNFL Live StreamPrime VideoNBC SportsCBS All AccessFubo.TVSlingNFL Game PassWe have a chance to sweep the Patriots for the first time since 1999. 👀@TicketMaster | #BUFvsNE— Buffalo Bills (@BuffaloBills) December 23, 2020
