Every Tuesday, PFF will be releasing its list of the lowest-graded players at each NFL position for that week. But Senior Analyst Sam Monson gets a jump on that by picking out 10 individual performances from Sunday’s games that stood out for just how bad they were.

Here are the 10 worst performances from Sunday’s Week 5 action:

1. Billy Turner, T, Miami Dolphins

A backup guard being asked to start at left tackle is unlikely to go well, and it went very not well for Turner and the Miami Dolphins in their loss to Tennessee. It’s tough to be too hard on Turner, who was simply out of his depth, but he surrendered three sacks, two hits and four hurries for a total of nine pressures in only 27 pass-blocking snaps. Throw in a penalty and some ugly run blocking and you have one of the worst days of the weekend.

2. D’Qwell Jackson, LB, Indianapolis Colts

Jackson missed four tackles in the win over the Bears, tied for the most among linebackers on Sunday, but he also had a poor day in coverage, allowing a catch every time he was targeted. As a smaller linebacker, he has never held up too well against the run when linemen have come to attack him, and Chicago now has one of the league’s best interior trios in the league. They consistently eradicated him at the second level.

3. Rey Maualuga, LB, Cincinnati Bengals

It’s difficult in games like this to see what the Bengals see in Rey Maualuga, who had one of his uglier performances. He was almost blanked from the stat sheet entirely, but for one lone tackle, and in coverage he coughed up 19 yards and a touchdown on two targets. Effectively he was just an obstacle out there in the middle of the Bengals defense for the Cowboys to play around, but rarely looked like actually affecting the play.

4. T.J. Clemmings, T, Minnesota Vikings

It didn’t seem like there was much room for the Vikings to get worse at left tackle from Matt Kalil after he went down hurt. Enter T.J. Clemmings, and the complete disproval of that notion. Against the Texans this week Clemmings surrendered two sacks, a penalty and was simply abused by Houston defensive end Jadeveon Clowney at the point of attack in the run game. On runs to either side of Clemmings’ block, Minnesota averaged 1.2 yards per carry, and 0.8 of those came after contact. The Vikings had yet another impressive win, but their offensive line is still an issue.

5. Johnathan Joseph, CB, Houston Texans

With Stefon Diggs out due to an injury, the Vikings' passing offense was missing a major weapon, but Joseph wasn’t able to stop the players who were asked to pick up the slack. Joseph was thrown at four times, allowing a catch on all of them for a total of 74 yards and a touchdown.

6. Brock Osweiler, QB, Houston Texans

This was not a good week for the Texans, who were throttled by the Vikings on the road. Osweiler was actually pressured more than he was kept clean, feeling heat on 24 of his 46 dropbacks. When he was hurried, his passer rating was just 18.8, and he completed only 25 percent of his passes. Read more here about the struggles of Osweiler, who has regressed since his strong Week 1 debut.

7. Ross Cockrell, CB, Pittsburgh Steelers

Cockrell has been playing well this season for Pittsburgh, but he was just completely unable to handle one-on-one coverage with Jets wide receiver Brandon Marshall, who was fresh off giving Seattle star CB Richard Sherman all he could handle a week ago. Marshall beat Cockrell for 96 yards on seven catches, catching a touchdown in the process. Cockrell did break up a couple of passes, but he was firmly on the losing end of his battle.

8. David Parry, NT, Indianapolis Colts

Colts second-year NT David Parry just looks a little too lightweight to hold up in the trenches at the NFL level, and he was controlled consistently against what may be the league’s best interior line now in the Chicago Bears. Parry managed one hurry in 29 pass-rushing snaps and was washed out against the run on just 14 snaps.

9. Ty Sambrailo, OT, Denver Broncos

Sambrailo made Atlanta edge rusher Vic Beasley look like Von Miller, giving up three sacks, a hurry and a penalty before finally being called ashore by the Broncos and benched later in Denver's loss. Sambrailo has now started three games for the Broncos, and his two at right tackle have been little short of disastrous.

10. Todd Gurley, RB, Los Angeles Rams

Gurley hasn’t had a whole lot of help this season, to put it mildly, but this week he was a contributing factor to his own problems, putting the ball on the ground twice on only 23 carries. A dropped pass didn’t help his cause as a receiver, and while he made a couple of big plays, the mistakes from trying to do too much were poor.
