2018 New England Patriots season
In the 2018–19 playoffs, the Patriots defeated the Los Angeles Chargers in the Divisional round 41–28, and advanced to the AFC Championship game for a record eighth-straight time. The Patriots defeated the Chiefs 37–31 in overtime to go to the Super Bowl for the third straight time, becoming only the third team in NFL history to appear in three consecutive Super Bowls (after the 1990–93 Buffalo Bills and the 1971–73 Miami Dolphins). In Super Bowl LIII, they will face the Los Angeles Rams at Mercedes-Benz Stadium in a rematch of Super Bowl XXXVI, in which the Patriots defeated the then-St. Louis Rams in a shocking upset 20–17. The Patriots will attempt to win their sixth Super Bowl championship, hoping to tie with the Pittsburgh Steelers for most Super Bowl championships.
