One key thing to know about every NFL Week 15 game

Six AFC teams are 7-6, the most at this point in any season in either conference. And six NFC teams are 6-7, which is more in either conference at this point in the season since the merger.

Only two teams, the Carolina Panthers and New England Patriots, have been eliminated from playoff contention.

Here’s a look at some interesting facts entering Week 15.

Chargers (5-8) at Raiders (5-8), 8:15 p.m., Amazon Prime: Easton Stick becomes the 55th different starter at quarterback this season. He replaces the Chargers’ Justin Herbert, who fractured his index finger against the Broncos and will miss the rest of the season.

Vikings (7-6) at Bengals (7-6), 1 p.m., NFL Network: In three starts in place of Joe Burrow, Jake Browning has passed for 856 yards and his 79.3 completion percentage over that span is the highest since 1950 for a quarterback in his first three career starts.

Steelers (7-6) at Colts (7-6), 4:30 p.m., NFL Network: After two straight losses at home to Arizona and New England — teams with all of four wins between them at the time — the Steelers (7-6 after a 6-3 start) mercifully hit the road. Hanging in the balance over the last few games of the season: averting the first losing season in Coach Mike Tomlin’s career.

Broncos (7-6) at Lions (9-4), 8:15 p.m., NFL Network: Detroit has lost two of its last three games, with Jared Goff no longer playing as well as he did early in the season. That makes this a poor time to face a steadily improving Broncos defense that used timely blitzes against the Chargers.

Falcons (6-7) at Panthers (1-12), 1 p.m., Fox: Atlanta has lost five one-score games, and Younghoe Koo — the league’s most accurate kicker with one miss coming into last week’s game — missed field goals from 50 and 52 yards in the 29-25 loss to Tampa Bay.

Bears (5-8) at Browns (8-5), 1 p.m., Fox: In five games since being traded to Chicago, defensive end Montez Sweat has a team-best 3.5 sacks and helped the Bears rise to become a top five defense (total defense, pass defense and takeaways) over that span.

Buccaneers (6-7) at Packers (6-7), 1 p.m., CBS: In the Packers’ loss to the Giants on a walk-off field goal, an opponent rushed for more than 200 yards on Green Bay’s defense for the fourth time this year. Saquon Barkley had 86 yards on 20 carries with two touchdowns.

Jets (5-8) at Dolphins (9-4), 1 p.m., CBS: Miami could have become the second AFC team to get to 10 wins, but the Titans’ rise from the crypt (with a chance of winning as low as 0.4 percent when they trailed 27-13 with 3:08 left, according to Next Gen Stats) was a Monday night shocker. Miami’s loss no doubt left the Chiefs, Ravens and Bills rejoicing in the tightly packed AFC battle for the No. 1 seed.

Chiefs (8-5) at Patriots (3-10), 1 p.m., Fox: Rashee Rice and Travis Kelce accounted for 20 of Patrick Mahomes’s 43 pass attempts (hauling in 13 for 155 of Mahomes’s 271 passing yards against Buffalo), with no other receiver targeted more than four times. Seven times this season, the team has failed to score more than 20 points in a game. As for the Bill Belichick coaching watch, New England plays road games in Denver and Buffalo before the season-ender at home against the Jets.

Giants (5-8) at Saints (6-7), 1 p.m., Fox: Just when the Giants need a folk hero, here comes Tommy DeVito (Tommy DeVito!). Among his accomplishments: He’s the first undrafted rookie QB in NFL history to win three straight starts without an interception; the first undrafted rookie QB in NFL history with a 100-plus passer rating in three straight starts; and the first Giants QB to win three straight starts with a 100-plus rating and zero interceptions since Fran Tarkenton in 1970. Improbably, the Giants are in the NFC playoff picture after winning their third game in a row Monday.

Texans (7-6) at Titans (5-8), 1 p.m., CBS: Houston’s defense struggled, giving up 301 passing yards to the Jets’ Zach Wilson while, on offense, it lost wide receiver Nico Collins to a calf injury and QB C.J. Stroud to a concussion. Davis Mills would be the 56th different QB starter this season if Stroud isn’t cleared to play.

49ers (10-3) at Cardinals (3-10), 4:05 p.m., CBS: Maybe it’s not outrageously hyperbolic to say “Brock Purdy” and “Joe Montana” in the same sentence any more. Purdy has connected on 70 percent or more of his passes in seven consecutive games, joining Montana (whose mark of eight in 1989 would seem reachable for Purdy against Arizona), Sam Bradford (seven, 2016) and Drew Brees (seven, 2016) as the only NFL QBs to do so in seven or more consecutive games.

Commanders (4-9) at Rams (6-7), 4:05 p.m., CBS: Five of the 14 interceptions thrown by Washington QB Sam Howell have come in the last five games, with a pick-six in each of the last three games. The record for consecutive games throwing a pick-six is four, set by Houston QB Matt Schaub in 2013.

Cowboys (10-3) at Bills (7-6), 4:25 p.m., Fox: Dallas is on a five-game roll and has a rookie kicker (Brandon Aubrey) who is 30-30 on his field goal attempts and, against the Eagles, was successful from 45, 50, 59 and 60 yards. No kicker had made two from 59 or beyond in a game before. That may be important given that each of Buffalo’s losses has been by six or fewer points (with two in overtime).

Ravens (10-3) at Jaguars (8-5), 8:20 p.m., NBC, Universo: Odell Beckham Jr. is emerging as a productive receiver for Baltimore with Mark Andrews absent. Beckham caught four passes for 97 yards, including three for more than 15 yards, in the OT victory against his former Rams teammates.

Eagles (10-3) at Seahawks (6-7), 8:15 p.m., ABC, ESPN, ESPN2, ESPN Deportes: Philly has been outscored 75-32 by San Francisco and Dallas, their direct competition for the NFC’s No. 1 seed, and has given up 34, 42 and 33 points in its last three games. In those games, opponents have scored on 19 of their 30 possessions (13 touchdowns, six field goals).
