The drama about the final teams that would make the N.F.L. postseason was not cleared up until the last possible moment of the regular season, when the Las Vegas Raiders beat the Los Angeles Chargers on Sunday night on a field goal on the last play of overtime to claim one of two remaining wild card berths in the A.F.C.
The Raiders’ 35-32 defeat of the Chargers ended the season for Los Angeles, and because the Indianapolis Colts (9-8) were upset by the Jacksonville Jaguars (3-14) earlier on Sunday, the Pittsburgh Steelers (9-7-1) sneaked into the playoff field on the strength of a win over the Baltimore Ravens.
