A disappointing performance on both sides of the ball, the Ravens looked out of sync and confused at times, something that they'll have to deal with this year after revamping the roster during the offseason.
There were some Ravens who had impressive performances, but most of the team struggled.
Check out the grades for each Ravens player against the Broncos.
Joe Flacco: B-
Things could have been better for Flacco, who did throw for 362 yards and two touchdowns, but on a career-high 62 attempts.
He completed just 34 passes, although his receivers' inconsistencies prevented him from easily topping 40 completions. His second interception to Broncos linebacker Danny Trevathan proved to be the nail in the coffin for the Ravens, and Flacco's inconsistencies contributed to the offense's struggles.
Flacco did make a few nice throws, however, and was asked to do too much in the second half as the Ravens trailed for the majority of the half.
Ray Rice: B+
He had a very pedestrian night statistically, gaining 36 yards on 12 rush attempts and 35 yards on eight receptions, but it's the role he had in the offense that led to his grade.
Getting Ray Rice a total of 20 touches despite having a pass-heavy offense is a positive sign, as his touches should increase even more during games the Ravens throw the ball fewer than 62 times.
Bernard Pierce: C
Unlike Rice, Bernard Pierce's role in the offense was rather limited, and he was a nonfactor in the passing game.
He gained just 22 yards on nine attempts and failed to record a catch.
Vonta Leach: A-
Vonta Leach wasn't on the field for much of the game, but when he was, he was his usual self as a lead run blocker.
He also scored the first touchdown of the 2013 NFL season and finished the game with three receptions.
Kyle Juszczyk: C
The rookie fullback did not have any role in the offensive game plan, and he was limited to strictly special teams.
Torrey Smith: B+
The Broncos successfully eliminated Torrey Smith's deep-threat ability that showed during the 2012 divisional round game; however, Smith still had a rather impressive night given the circumstances, catching four passes for 92 yards.
Jacoby Jones: B
Prior to a knee injury in the second quarter that kept him out of the rest of the game, Jacoby Jones was making an impact in the passing game.
He caught three passes for 24 yards and appeared to be one of Flacco's go-to receivers.
Brandon Stokley: C+
Surprisingly, Brandon Stokley was Baltimore's most inconsistent receiver against Denver. He caught four passes but left yards on the field and had some miscommunications with Flacco.
Marlon Brown: A
Given that Marlon Brown was an undrafted rookie playing in his first NFL game, his four catches for 65 yards and one touchdown were more than impressive.
He was forced to play most of the second half due to Jones' injury, and his performance was one of the bright spots of Baltimore's loss.
Ed Dickson: D-
One of Baltimore's most inconsistent players on the field against Denver was Ed Dickson, who couldn't catch anything thrown his way.
He managed to catch just one pass for 13 yards, and while he was open on multiple occasions, his inability to hang onto the ball stalled many Baltimore offensive drives.
Dallas Clark: B-
He managed to catch seven passes for 87 yards in an extensive role in his first game with the Ravens, but his drop in front of the end zone before halftime proved to be costly.
Dallas Clark cost the Ravens a touchdown, and he also had another drop, although the hit by the defender caused the drop more than Clark did.
Billy Bajema: B-
He didn't contribute in the passing game as expected, but he was his usual efficient self as a run blocker.
Bryant McKinnie: B-
Compared to the rest of the offensive line, Bryant McKinnie had a rather successful night. He struggled as a run blocker as usual, but overall, he played a pretty clean game.
Kelechi Osemele: D
He was Baltimore's worst offensive lineman, which was a surprise after a strong finish to the end of the 2012 season.
He received a grade of minus-3.3 from Pro Football Focus (subscription required), the worst grade of any Ravens lineman.
Gino Gradkowski: C+
In his first career NFL start, Gino Gradkowski played just about as expected, although his inability to get any push in the run game made it hard for the Ravens to have much success up the middle.
Marshal Yanda: A
Just like his typical self, Marshal Yanda was Baltimore's most efficient offensive lineman, and perhaps the team's best offensive player period.
His success against Denver was overshadowed by a poorly played game by the offensive line as a whole.
Michael Oher: A-
His grade is more based on the play of his backup—Ricky Wagner—as Michael Oher's absence due to an ankle injury proved costly for Baltimore's offense.
Perhaps Oher is more valuable to the Baltimore offense than perceived.
Ricky Wagner: C-
Wagner dealt with the tough task of being thrown into the starting lineup in his first NFL game, and while he did have some success as a run blocker, his struggles in pass protection made it hard for Joe Flacco to have enough time to make throws from the pocket.
A.Q. Shipley: C
He did not take any offensive snaps and was limited to just special teams duties.
Marcus Spears: B
In his first game with the Ravens, Marcus Spears had a rather large role with starting defensive end Arthur Jones out.
He excelled at what he does best—run defense—and his impact was felt.
Chris Canty: B
Like Spears, Chris Canty was forced into a large role in his first game with the team, but he rose to the occasion.
He provided value as a pass-rusher, and earned the Ravens' best pass-rushing grade, according to Pro Football Focus (subscription required).
DeAngelo Tyson: C
He was on the field for just one defensive play, and he was limited to special teams like many other players.
Haloti Ngata: A-
Despite going through the game rather quietly, Haloti Ngata's impact was felt in both the run and pass game.
He was able to get good push against a depleted interior offensive line for the Broncos and was one of Baltimore's best defenders.
Terrence Cody: C+
Forced into a large role with Brandon Williams sidelined, Terrence Cody failed to live up to the level of play he produced during the preseason, but he still provided a passable showing.
Elvis Dumervil: B+
In his debut with the Ravens, Elvis Dumervil was effective in both pass and run defense.
Paired with Terrell Suggs, Dumervil was able to work on the right side of the offensive line and forced three quarterback hurries.
Terrell Suggs: A-
In his first game in which he was fully healthy after an Achilles injury in 2012, Suggs' effectiveness as a pass-rusher was noticeable.
His performance would have been more impressive if he could have recorded more than one sack, but his presence was still felt.
Courtney Upshaw: C-
He was reliable as usual in run defense, although it was evident that he didn't improve as a pass-rusher during the offseason.
It's starting to look like Courtney Upshaw will be a one-dimensional player in the NFL.
Pernell McPhee: B-
He was only on the field for 13 plays, but he managed to make his presence felt in run defense.
Arthur Brown: C+
He failed to assert himself in the defensive rotation, and the Ravens' lack of urgency to use him in pass defense was a bit of a concern.
Daryl Smith: C
After a strong preseason, Daryl Smith was rather inconsistent, particularly in coverage. Baltimore's linebackers as a whole struggled to cover the middle of the field, and Smith contributed to those issues.
Josh Bynes: C-
Despite his inability to cover in the middle of the field, the Ravens still surprisingly opted to keep him in for most of the game.
His struggles in pass defense were noticeable, and he was exploited several times.
Lardarius Webb: A-
Overshadowed by a porous night by the Baltimore secondary, Lardarius Webb's first meaningful game since last October was nearly flawless.
It looks like his ACL is fully healed and he'll be fine for the 2013 season.
Corey Graham: D-
After a strong showing in the 2012 divisional round against the Broncos, Corey Graham struggled mightily, and his inability to cover in both the slot and the outside proved to be one of the reasons why the Ravens struggled so much defensively.
Jimmy Smith: D
He was one of the worst players for the Ravens against the Broncos, and his exploitation in the passing game was a concern, as his inability to have any success in man coverage looked even worse than last year.
Chykie Brown: C
Despite the Ravens' struggles in the secondary, Chykie Brown didn't touch the field as a defensive member and was limited to special teams.
Michael Huff: D
Things couldn't have been much worse for the veteran, who was Baltimore's worst defender despite high expectations upon his arrival in Baltimore.
Praised for his versatility and coverage ability, Michael Huff was embarrassed in his team debut.
Matt Elam: C+
In a very limited role (15 plays), Matt Elam didn't get exposed much in the passing game, as Denver quarterback Peyton Manning primarily targeted Baltimore's cornerbacks.
He didn't make a noticeable impact on any play, but he also didn't necessarily have many negative plays, which is a plus for a Ravens secondary that allowed seven touchdown passes.
James Ihedigbo: B+
In his first game as Baltimore's starting strong safety, James Ihedigbo performed rather admirably, and only a few mishaps in the middle of the field overshadowed a solid showing for the veteran.
Brynden Trawick/Anthony Levine: C
Neither recorded a defensive snap, and both were limited to special teams.
Justin Tucker: A
He connected on both of his short field-goal attempts, and all six of his kickoffs resulted in touchbacks. A flawless night for the second-year kicker.
Sam Koch: A
He had a busy night, punting the ball nine times, but his average of 50.7 yards per punt earned him a high grade.
