A final look at the Broncos’ 24-17 win over the Pittsburgh Steelers on Sunday:

1. Sunday was the fourth regular season game in Steelers quarterback Ben Roethlisberger’s career in which he attempted at least 55 passes (he was 41 of 56 for 462 yards). That meant plenty of work for the Broncos’ cornerbacks. In man coverage: Chris Harris (6 of 9, 52 yards; his interception came in zone coverage), Bradley Roby (9 of 10, 163 yards, one touchdown), Tramaine Brock (3 of 5, 13 yards) and Isaac Yiadom (1 of 4, 13 yards).

2. The Broncos used a rush-four-and-cover game plan. They rushed five or more players on only 11 of Roethlisberger’s 62 drop-backs (17.7 percent). Roethlisberger was 6 of 11 for 146 yards (97 coming on the touchdown) and one interception against extra rushers. The Broncos had two sacks (Shaq Barrett and Von Miller/Shelby Harris), two other knockdowns (Harris and Adam Gotsis) and two pressures (Barrett and Harris). Bradley Chubb was kept off the pressure chart for the first time since Week 5 at the Jets.

3. The Broncos’ defense played a season-high 78 snaps (the previous high was 72 in the first Kansas City game and against the Rams and Chargers). Nineteen defenders played at least 22 snaps, led by all 78 for safeties Justin Simmons and Darian Stewart.

4. The Steelers rushed five or more players on 19 of Broncos quarterback Case Keenum’s 32 drop-backs (a season-high 59.4 percent; Arizona was at 40 percent in Week 7). Keenum was 6 of 16 for 79 yards and one touchdown against pressure. Pittsburgh had two sacks, three other knockdowns and three pressures. On the two sacks, linebacker Vince Williams got by right guard Elijah Wilkinson (1.88 seconds) and Wilkinson/center Connor McGovern were bull-rushed in 2.05 seconds.

5. The Broncos’ winning drive had several highlights: Phillip Lindsay gained 18 yards on second-and-10 thanks to blocks from left tackle Garett Bolles (on linebacker Anthony Chickillo) and left guard Billy Turner (on defensive end L.T. Walton). On the next play from scrimmage (first-and-15), tight end Jeff Heuerman started in pass protection before running down the right seam wide open (15 yards) because linebacker Jon Bostic buzzed to the flat when Keenum looked right toward fullback Andy Janovich on a wheel route. On the next play, receiver Emmanuel Sanders caught at a 14-yard pass when he started from the left slot and was open when Bostic bit on Keenum’s eyes toward the flat.

6. Having tied the game at 10 entering halftime thanks to a fake field goal that resulted in a touchdown, the Steelers had possession to start the second half. But the Broncos forced a punt thanks to rookie receiver James Washington’s illegal block in the back on Simmons (a terrible call) and linebacker Todd Davis’ stop on Antonio Brown (1-yard gain) when he dodged the block attempt of left guard Ramon Foster. Another third-quarter turning point: Leading 17-10, the Steelers used rushes of 11, four and eight yards to move to the 46. But rookie linebacker Kieshawn Bierria had a run stuff on first down and two plays later, on third-and-3, Chris Harris dropped into zone coverage and intercepted Roethlisberger. The Broncos tied it two plays later. Related Articles Broncos Briefs: Phillip Lindsay doubtful to play Sunday, but progressing from toe injury

7. Stewart was fortunate on two big plays. On the opening play of the second quarter, the Steelers had third-and-1 from the Broncos’ 24. Stewart’s responsibility was tight end Xavier Grimble. Stewart bit on Roethlisberger’s play fake, leaving Grimble wide open four yards downfield. He was on his way to a touchdown but safety Will Parks met him at the goal-line to force a fumble through the end zone (touchback and Broncos ball). And on the final play of the third quarter, Stewart took a bad angle after Conner caught a pass, but Stewart recovered the fumble that was forced by a Roby hit.

8. We booked the Broncos for only three missed tackles — two by Harris and one by Shelby Harris. It was their lowest total since three at Baltimore in Week 3.

9. On third down in the second half, Roethlisberger was 2 of 6 for 20 yards and two interceptions. On the final drive, the Steelers converted a third-and-6 (19 yards to JuJu Smith-Schuster) when the Broncos changed their coverage — Yiadom dashed backward at the snap and Simmons was assigned to Smith-Schuster. Roethlisberger lofted a perfect pass over Simmons. Four plays later, though, Harris intercepted Roethlisberger in the end zone.

10. The Broncos’ downfield passing game isn’t clicking. In the last three games, Keenum is 2 of 10 on passes that travel at least 16 yards in the air. He was 1 of 5 against the Steelers, but the lone completion was 38 yards to Sanders. On the next play, Sanders started by chipping pass rusher T.J. Watt before leaking into the end zone and then following a scrambling Keenum toward the sideline before making the catch.
