Grading Bears performance vs. Dolphins

Quarterback: A+Let's start with the obvious: Justin Fields set the NFL record for rushing yards with a quarterback with 178. It doesn't get much better than that. The highlight was a 61-yard sprint down the sideline that cut Miami's lead to 28-25 early in the third quarter. While Fields threw for only 123 yards, he did have 3 TD passes, 2 of which when to Cole Kmet. On the first one, he perfectly executed a run fake to Khalil Herbert, then hit Kmet in the flat. Despite the loss, it was an incredible day that Bears fans will remember for quite some time.

Running backs: DIt was tough sledding for David Montgomery and Khalil Herbert, who averaged just 2.81 yards per carry on a combined 21 carries.

Receivers: CTough one to grade here because Darnell Mooney hauled in a season-high 7 receptions (1 for a TD), and Cole Kmet had the first multi-TD game of his career. Mooney, Kmet and others also made key blocks during many of Fields' 15 rushing attempts. The downside is that guys still aren't getting open consistently enough to make the Bears' offense everything it can be.

Offensive line: BThe line kept Justin Fields clean most of the game, holding their blocks long enough to allow him to escape on numerous occasions. Run blocking was very mediocre, however.

Defensive line: FDolphins QB Tua Tagovailoa attempted 30 passes, was never sacked and was hit just twice. The lack of pressure allowed Miami's wide receivers to run wild.

Linebackers: DLake Zurich HS product Jack Sanborn was solid in the run game, but the rest of this group underperformed.

Secondary: DKindle Vildor committed a bad pass interference call on Tyreek Hill on Miami's first drive, setting the tone for the game. Hill (7 catches, 143 yards) and Jaylen Waddle (5-85) shredded the secondary all day. One of the few positives was Jaylon Johnson's break up of a third-down pass intended for Waddle on Miami's last drive.

Special teams: FMiami's blocked punt midway through the second quarter gave the Dolphins a 21-10 lead. That breakdown may have been the difference in the game. It just can't happen.

Coaching: COffensive coordinator Luke Getsy called a fantastic game. Long, clock-churning drives kept the Bears in it and kept Miami's offense off the field. On the flip side, we saw no creativity on defense. The Bears' vanilla, soft D never challenged Tua Tagovailoa and he made them pay.
