Ravens' report card at the Dolphins

Grading the Baltimore Ravens in their 28-13 win against the Miami Dolphins:

Quarterback: Joe Flacco completed a season-high 75.8 percent of his passes (25 of 33) and accounted for three touchdowns (two passing and one rushing). He threw for 269 yards -- 255 of which came after the first quarter -- against the NFL's No. 2 pass defense. His 15-yard run jump-started a 97-yard drive and he converted a fourth-and-one at his own 34-yard line to extend touchdown drive that gave the Ravens their first lead of the game. Flacco's only mistake was throwing an interception in the end zone (his first pick in four games). That wouldn't have happened if Steve Smith had caught a touchdown pass the previous play. Grade: A.

Running backs: It was tough sledding for most of the game because Justin Forsett was clearly not at full strength after injuring his knee a week ago. The Ravens wore down the Dolphins and gained 107 yards in the fourth quarter. But the Ravens' running backs didn't break many tackles Sunday. Forsett gave the Ravens some breathing room with a 2-yard touchdown in the fourth before breaking a 44-yard run, the longest play of the game. Rookie Lorenzo Taliaferro, who moved back into the primary backup role, totaled 55 yards (35 rushing, 20 receiving) and Bernard Pierce added runs of 24 and 27 yards in the final five minutes of the game. Fullback Kyle Juszczyk got beat in pass protection, and it nearly caused Flacco to fumble (replay overturned it). Grade: B-plus.

Wide receivers/tight ends: The biggest compliment is the Ravens didn't miss Torrey Smith, whose right knee swelled up in pregame warm-ups. Steve Smith showed quickness with a quick cut to get open for a one-yard touchdown. Kamar Aiken recorded career highs with six catches for 65 yards, and he scored his second career touchdown. Marlon Brown converted a third-and-11 by leaping over a defender. Even tight end Phillip Supernaw, who wasn't in the game program because he was just promoted from the practice squad, caught a 29-yard pass. The only knock on the receivers was Steve Smith dropping a touchdown in the second quarter. Grade: A-minus.

Offensive line: This was another strong performance by the line, which opened up holes late in the game and provided good pass protection. The Ravens gained 160 yards before contact, the second-most in the NFL this week and a sign that the line created some running lanes. Flacco was also just sacked and hit once in the game. Guards Marshal Yanda and Kelechi Osemele excel in the run game because of how they drive back linemen and finish blocks. There were some mistakes. Center Jeremy Zuttah was pushed back to thwart an early third-and-1, and right tackle Rick Wagner failed to pick up a blitz on a play that Flacco floated a pass to the end zone and was intercepted. Grade: A-minus.

Defensive line: The Ravens did remarkably well in their first game without Pro Bowl defensive tackle Haloti Ngata, who is suspended for the rest of the regular season. The run defense limited the Dolphins to 63 yards, and if you take away that 15-yard gain on the first play, it held Miami to 3.2 yards per carry the rest of the way. Defensive end Chris Canty had his best game as a member of the Ravens and finished with four tackles. The Ravens' youthful combination of Timmy Jernigan and Brandon Williams didn't budge much after the first quarter. Grade: A.

Linebackers: All of the Ravens' season-high six sacks came from the linebackers group. Elvis Dumervil recorded 3.5 sacks, his most in two seasons with the Ravens. Terrell Suggs contributed a sack in his fourth straight game. And an unblocked C.J. Mosley delivered a sack in the red zone to force the Dolphins to settle for a field goal in the fourth quarter. Mosley also led the Ravens with eight tackles, including three on third down that ended drives. The biggest negative is Suggs and Courtney Upshaw both getting flagged for being offside. Grade: A.

Secondary: What helped the secondary the most was the Dolphins' reluctance to throw deep even though they have strong-armed Ryan Tannehill and speedy receiver Mike Wallace. The Ravens weren't beaten badly on many throws. Their defensive backs stuck with the receivers, although they never made an aggressive move to make a play. The secondary combined for no pass breakups and no interceptions. Only one pass play went longer than 20 yards, and it came off a screen pass to Charles Clay. Matt Elam missed another tackle. Grade: B.

Special teams: The Ravens committed two penalties on special teams. The biggest error was Danny Gorrer's holding penalty on a punt return, which pushed the Ravens to their own 3-yard line. Other than that, it was a quiet day from the Ravens' special teams. Justin Tucker recorded two touchbacks and didn't attempt a field goal. Sam Koch netted 42.3 yards, but he didn't place any of them inside the 20-yard line. Jacoby Jones was a nonfactor on punt returns. Grade: B-minus.
