Ravens had NFL's worst offensive showing in Marc Trestman's debut

The debut of Marc Trestman's offense with the Baltimore Ravens was just about as bad as it could go. In fact, it was the worst offensive showing in Week 1 of the 2015 season.

The Ravens managed 173 total yards in the 19-13 loss to the Denver Broncos, which made them the only team that failed to crack 200 yards. Baltimore had the fewest net passing yards (100) and the eighth-fewest rushing yards (73).

This was a tough matchup because the Broncos should be a top-five defense this season. This just wasn't the first step that the Ravens had envisioned coming off a season in which they set franchise records for total yards and points.

Trestman, who was hired to replace Gary Kubiak, had mixed results in his two seasons as the Chicago Bears head coach. The Bears had the No. 8 offense in 2013, but they dropped to No. 21 in 2014.

The Ravens' struggles on offense Sunday was as much about execution by the players as Trestman's playcalling. The Ravens couldn't protect Joe Flacco, who was pressured on half of his dropbacks. Baltimore couldn't create any running lanes until the final drive. And the wide receivers failed to get any consistent separation.

As a result, the Ravens were one of three offenses who didn't score a touchdown (the Broncos and Minnesota Vikings were the others).

"We've got a lot to work on obviously," Flacco said. "We're a lot better than that. A pretty poor showing, but you got to keep your head up and you got to move on quick because in this league. The next one comes up on top of you like that. So, we've just got to make sure we stay confident and bounce back as soon as possible."

This also marked the worst debut of any Ravens offensive coordinator. There have been six coaches who previously held the title of offensive coordinator for the Ravens -- Matt Canvaugh, Jim Fassel, Rick Neuheisel, Cam Cameron, Jim Caldwell and Gary Kubiak -- and only Cavanaugh (223 yards) and Caldwell (278) watched their offenses get held below 300 yards in their first games as playcallers.

The Ravens, though, have had their troubles with these changes. They are now 1-6 in debuts of new offensive coordinators, averaging just 14.2 points per game.
