Drafted into service: The four healthy members of the Lions' 2018 draft class got extended playing time for need, not show. Guard Frank Ragnow (first round) and defensive tackle Da'Shawn Hand (fourth) started as they have all season. Hand left early with a knee injury. Safety Tracy Walker (third) played 43 snaps, the same total as veteran Glover Quin. Tyrell Crosby (fifth) took over at right tackle when Rick Wagner went out with a concussion and played 35 snaps, with some of them earlier as an extra lineman. – Mike O'Hara
High marks: How good was Detroit's defense Sunday in Arizona? They had 14 players on that side of the ball receive a positive grade from Pro Football Focus for their performance. That's the most they've had all season. Cornerback Darius Slay led the way, as he allowed just three receptions (long of 11 yards) on the nine times he was thrown at and had an interception, touchdown and defended two other passes. – Tim Twentyman
Diggs, happy returns: Quandre Diggs has returned punts occasionally in the past, but Sunday was the first time he did it this season. He handled two punts with a four-yard return and a fair catch, and he looked 100 percent comfortable in the role. It might not seem like much, but having a player of such versatility provides valuable insurance. – Mike O'Hara
Swarmed: Cardinals running back David Johnson is one of the best dual threat backs in the NFL, but he was swarmed by the Lions' defense in the pass game. Whether it was screen passes, flair passes or dump offs, Detroit's defense was all over him. Johnson caught eight passes in the game for a total of 12 yards. With a long of 10 yards, the other seven catches accounted for just two yards. Detroit had their eye on Johnson all game, and flew to the ball Sunday whenever he was targeted. – Tim Twentyman
High 5's, Patricia-Belichick: Head coach Matt Patricia no doubt would like the Lions to have a better record than 5-8, but it's been good enough to tie Bill Belichick's win total in his first season as head coach of the Patriots. The Patriots were 5-11 in 2000 and have never had another losing season under Belichick. Belichick was 6-10 in 1991, his first season as head coach of the Browns. – Mike O'Hara
Tough at the top: Second-year wide receiver Kenny Golladay got a true look Sunday at what it's like to be the No. 1 player targeted by a defense. Not only did he see plenty of All-Pro cornerback Patrick Peterson in the game, but the Cardinals rolled coverage his way early and often Sunday, obviously with the plan to not let the ultra-talented receiver beat them. Golladay was targeted just four times in the game and caught two passes for five yards. It will count as a continued learning experience for Golladay, as the more he sees this kind of treatment, the quicker he'll learn how to counteract it. – Tim Twentyman
Snacks effect: Detroit produced their fourth game with 65 or fewer rushing yards allowed this season, tied for the second most in the league. Those four performances have all come in Detroit's last five games, and all since defensive tackle Damon Harrison arrived via trade in mid October. Since his arrival, the Lions are allowing on average just 94.5 rushing yards per game. If that total was projected over the entire season, it would be sixth best in the NFL. – Tim Twentyman
