What We Learned From Week 18 in the N.F.L.

Indianapolis dusted off some old-school football dogma by bludgeoning defenses with Taylor’s runs to dig itself out of a 1-4 hole early in the season. Taylor’s vision, power and speed had been unparalleled in wins over playoff-bound teams.Against the Buffalo Bills, Taylor had a 204-yard, five-touchdown masterpiece. When Bill Belichick stacked the Patriots’ line to slow him, Taylor still earned 170 yards, including a late 67-yard blast that ended New England’s seven-game win streak. And with the Colts down to what was essentially its second-string offensive line in December, Indianapolis stymied the Cardinals, 22-16.And it was all for naught because Indianapolis couldn’t beat Jacksonville, the team with the worst record in the N.F.L.That’s about embarrassing as it gets.Playoff PictureA.F.C.No. 1 Tennessee Titans (12-5) — ByeNo. 2 Kansas City (12-5) vs. No. 7 Pittsburgh Steelers (9-7-1), Sunday, 8:15 p.m., NBCNo. 3 Buffalo Bills (11-6) vs. No. 6 New England Patriots (10-7), Saturday, 8:15 p.m., CBSNo. 4 Cincinnati Bengals (10-7) vs. No. 5 Las Vegas Raiders (10-7), Saturday, 4:30 p.m., NBCN.F.C.No. 1 Green Bay Packers (13-4) — ByeNo. 2 Tampa Bay Buccaneers (13-4) vs. No. 7 Philadelphia Eagles (9-8), Sunday, 1 p.m., FoxNo. 3 Dallas Cowboys (12-5) vs. No. 6 San Francisco 49ers (10-7), Sunday, 4:30 p.m., CBSNo. 4 Los Angeles Rams (12-5) vs. No. 5 Arizona Cardinals (11-6), Monday, 8:15 p.m., ESPN and ABCAll times Eastern.
