The 32 things we learned from Week 13 of the 2021 NFL season:

1. The Arizona Cardinals maintained the league's best record (10-2) while welcoming back QB Kyler Murray and WR DeAndre Hopkins, who teamed up for a 20-yard TD in Chicago after both missed five weeks with injuries. Murray burned the Bears for four scores (2 passing, 2 rushing) as the Cards remained unbeaten on the road.

2. Arizona's 33-22 triumph at Soldier Field made the Cardinals the third team to win seven straight road games by double-digit margins in one season. The Cards will make history if they can do it again in Week 15 … at Detroit.

3. All-Pro Cardinals S Budda Baker won't get the same flak he did for getting run down by Seattle's DK Metcalf last year … but, Budda, shouldn't you be able to juke Andy Dalton to get that elusive pick-six?

4. Have a day, T.J. Watt. The All-Pro pass rusher and league's highest-paid defensive player affirmed his bona fides by notching 3½ sacks of Ravens QB Lamar Jackson in the Pittsburgh Steelers' 20-19 escape from Baltimore. Watt, who's missed two games with injuries and spent last week on the reserve/COVID-19 list, has an NFL-high 16 sacks in just 10 games. He's on pace to collect 24, which would break Hall of Famer Michael Strahan's single season record – 22½, set in 2001.

5. The Ravens (8-4), who maintain a one-game lead in the AFC North, chose to go for the win with a two-point attempt after Jackson's TD pass to WR Sammy Watkins made the score 20-19 with 12 seconds left. However Jackson – with Watt in his grill – didn't give wide-open TE Mark Andrews a good pass on the decisive play.

6. Steelers coach Mike Tomlin fired off a gem of a postgame quote when asked about Baltimore coach John Harbaugh's gamble: "They aggressively play analytics, so from that standpoint, they’re predicable."

7. Maybe Ben Roethlisberger, 39, is, too, the Pittsburgh quarterback left in tears after what could be his final game against the archrival Ravens at Heinz Field. Big Ben (236 yards and 2 TDs passing) would not confirm whether the 2021 season will be his last, but Sunday's game could mean he'll still be playing football well into January.
