10 worst performances from Sunday's Week 6 NFL action

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 6 action:

1. Ladarius Gunter, CB, Green Bay Packers

One of multiple Packers to make this list after their loss to Dallas, Gunter had the kind of game that puts job security at risk. Every time you looked up he was getting beaten in some way or other, and for the game he surrendered 119 yards on eight targets. When targeting Gunter, Dallas rookie QB Dak Prescott had a passer rating of 156.3, just two points away from perfect, and Gunter compounded his poor coverage with ugly run defense and a missed tackle. This was a week to forget for him.

2. Zack Sanchez, CB, Carolina Panthers

While Gunter was finding several creative ways to get beat, Sanchez was leaning on an old staple – the double move. This has been his kryptonite for as long as we have graded tape on him, and he was toasted by it again in Carolina's loss to the Saints, biting on the first move regularly and surrendering 183 yards, including 87 on a single reception.

3. Karlos Dansby, LB, Cincinnati Bengals

Any time you allow a perfect passer rating into your coverage, things did not go well in the game. Dansby was targeted five times and allowed a catch on every occasion, surrendering 95 yards and two touchdowns in Cincinnati's loss to New England, and adding a pair of missed tackles to his stat sheet for the day. Thankfully for the Bengals, he was only covering Patriots tight end Rob Gronkowski for one target (and it went for 32 yards), or who knows how bad the numbers could have been.

4. Halapoulivaati Vaitai, T, Philadelphia Eagles

At least on first look, the downgrade from the suspended Lane Johnson to the Big V for the Eagles at right tackle is a colossal one. Johnson had given up five total pressures in four games, across 275 snaps of action, but Vaitai surrendered five in Sunday's loss to the Redskins alone, on only 29 pass-blocking snaps. That would be bad enough if he was a match for Johnson in the run game, but he was no better there, giving the Eagles a big problem at the position all of a sudden with Johnson suspended for 10 games.

5. Michael Wilhoite, LB, San Francisco 49ers

There may not have been a defender more constantly out of position on Sunday than Wilhoite was in San Francisco's loss to the Bills. His reads and run fits were disastrous, and he is a big part of the reason Bills RB LeSean McCoy was able to go off for 140 rushing yards on just 19 carries (7.4 per carry). QB Tyrod Taylor added 70 rushing yards himself and the Bills as a team rushed for 314. Naturally, those weren’t all on Wilhoite, but there was no bigger culprit, and a pair of missed tackles didn’t help his cause.

6. Connor Barwin, DE, Philadelphia Eagles

Working primarily against Washington left tackle Trent Williams was always going to be a tough ask for Barwin this week, but he was practically erased from the game by the big tackle. He notched just two total hurries and two stops in the game, but was routinely dominated at the point of attack and he rushed the passer 31 times to get that output. Barwin was simply outmatched in this game, going up against one of the league’s best.

7. Austin Howard, T, Oakland Raiders

The Raiders have used five different players at right tackle this season, and during this week's loss to the Chiefs, Howard managed to make Dee Ford look like Dwight Freeney. He surrendered seven total pressures on 40 pass-blocking snaps and was responsible for the best game of Ford’s disappointing NFL career. Hopefully for his sake, Howard wasn’t playing back at 100 percent health, after having been out hurt, because if this was his best he’s in trouble.

8. Clay Matthews III, OLB, Green Bay Packers

Remember when Matthews used to be good? It’s been a while now, and this week marked yet another incredibly ineffective performance from the former All-Pro edge rusher. Matthews was shut out in terms of pass rush, despite 20 snaps of rushing after the QB, and he was little better in the run game, notching a solitary tackle to prove that he was in fact in the game at all. That, and his penalty for jumping offside.

9. Eric Reid, S, San Francisco 49ers

Reid was another member of the 49ers defense that proved entirely incapable of defending the Bills this week. He missed two tackles while being responsible for 50 yards and a touchdown on the plays in which he was primary coverage. Another player to surrender a perfect passer rating, he is one of several 49ers who will want to forget this game sooner rather than later.

10. Aaron Rodgers, QB, Green Bay Packers

Rodgers had his second ugly game of the season, and unlike Week 2 versus Minnesota, this one didn’t come against an elite defense. He was missing throws from the outset, either with poor ball location or being completely off-target. He missed high on a wide-open touchdown, threw an uncharacteristic poor interception that came on a bad read where he simply didn’t see the dropping defender, and fumbled the ball down by the Cowboys' goal line on a QB draw that really put the team in a hole. Rodgers right now is pushing to try and get out of this funk, and is only succeeding in sinking deeper into it. (For more on Rodgers' struggles, click here.)
