The Steelers' report card is a mess after a 31-10 loss to the Cleveland Browns.

Here are the marks:

Quarterback: Ben Roethlisberger admittedly did not play well against a team he normally owns. He led the Steelers to one meaningless touchdown, and his passer rating of 64.4 was almost doubled by Browns quarterback Brian Hoyer (113.0). Grade: D

Running backs: The Steelers controlled the game in the first quarter by running the ball successfully, and they finished with 138 rushing yards and averaged 4.3 yards a carry. The Steelers ran the ball three consecutive times inside the Browns’ 10-yard yard line early in the game but couldn’t score a touchdown: Grade: B-

Wide receivers: Antonio Brown showed up, catching seven passes for 118 yards and drawing a pass interference penalty that put the Steelers in position to score an early touchdown. The Steelers, however, are still too reliant on Brown as Markus Wheaton had just 33 receiving yards despite getting 11 targets. Lance Moore caught a touchdown pass but also had a drop: Grade: C-

Tight ends: Heath Miller was a non-factor in the passing game as he caught two passes for 19 yards. The 10th-year veteran also missed a block on a misdirection pitch early in the game and Le'Veon Bell was dropped for a short loss when the Steelers needed a yard for a first down. Grade: D

Offensive line: It couldn’t impose its will on a depleted Browns front seven in critical situations, most notably on the three running plays near the Browns’ end zone early in the game. What looked like a blown assignment on third down from the Browns’ 2-yard line left Cleveland linebacker Craig Robertson free to stop LeGarrette Blount well short of the end zone. Grade: D

Defensive line: The Browns exploded for 157 rushing yards in the final three quarters, and the Steelers' problems with stopping the run started up front. This unit continues to struggle with zone-blocking teams, and it’s hard to imagine the Steelers being any more than an average run defense this season and that’s if they make significant improvement. Grade: D

Linebackers: Lawrence Timmons led the Steelers with 10 tackles, but he struggled against the run, too. The Steelers didn’t get any quarterback pressures from their outside linebackers. Arthur Moats, who has been starting at right outside linebacker for the injured Jarvis Jones, did not record a tackle. Grade: D

Cornerbacks: The inconsistency of Cortez Allen continues. The fourth-year veteran struggled in pass coverage a week after playing his best game of the season. None of the Steelers’ three cornerbacks broke up any passes. They are not getting enough help from the pass rush, but this group has to play better. Grade: D

Safety: The play of Mike Mitchell was one of the few positives for the Steelers. Mitchell forced a fumble and also prevented a pair of catches with jarring hits that separated the receiver from the ball. Troy Polamalu had eight tackles, including one for a loss. But he appeared to be the one who blew the coverage on Browns tight end Jordan Cameron's 45-yard catch early in the second quarter. Grade: C+

Special teams: A botched hold on a field goal attempt helped turn the game in the Browns’ favor. Dri Archer consistently comes up short of the Steelers’ 20-yard line on the kickoffs he is able to return, and he has been a disappointment on special teams. Brad Wing posted a net average of 42.1 yards on seven punts. Grade: D

Coaching: The Steelers fell apart in the second quarter and coach Mike Tomlin couldn’t pull them out of their tailspin. Something is really off and it is incumbent upon Tomlin to pull the Steelers together. Todd Haley has to get much more out of an underachieving offense. His approach simply isn’t working. Grade: F
