Every Tuesday, PFF will be releasing its Team of the Week, representing the highest-graded players at each NFL position for that week. But Senior Analyst Sam Monson gets a jump on that by picking out the 10 least-impressive individual performances from Sunday’s games.

Here are the 10 worst performances from Sunday’s Week 16 action:

1. George Fant, T, Seattle Seahawks

George Fant this week looked very much like a basketball player asked to block some of the game’s best pass-rushers, and it didn’t go well. He surrendered two sacks and seven additional hurries across 58 snaps of pass blocking, and was flagged for holding, as well. Former basketball players may be cheap and athletic resources, but they have yet to prove themselves as being capable of playing tackle well at the NFL level.

2. Tracy Porter, CB, Chicago Bears

Tracy Porter surrendered four catches for 157 yards, meaning, on average, he was beaten for almost 40 yards per reception against the Redskins in Week 16. Porter was also flagged for defensive pass interference on a deep ball intended for DeSean Jackson in order to prevent another huge gain that would have made those numbers look even worse, and he missed a pair of tackles after the catch.

3. Ryan Shazier, LB, Pittsburgh Steelers

Games like this are why Ryan Shazier is not one of the game’s best linebackers yet. If you got the best of his performances consistently, he would be right up there, but a poor outing is never far away. Against the Ravens, Shazier surrendered 128 yards in coverage, as well as a touchdown from 11 targets, even if he did manage an interception. Even with that pick, he allowed a passer rating of 107.6 into his coverage, and six different Baltimore receivers beat him for receptions.

4. Ziggy Hood, DI, Washington Redskins

While the league’s best interior pass-rushers are applying constant pressure in games, Ziggy Hood came out of Washington's most recent battle with no pressure of any kind to his name. A pair of tackles is the only statistical evidence of his involvement in the game, as Hood was a complete and total non-factor across his 42 defensive snaps.

5. DaVonte Lambert, DE, Tampa Bay Buccaneers

In 57 snaps starting at defensive end for the Bucs this week, DaVonte Lambert missed almost as many tackles (one) as he made (two). In 28 pass-rushing snaps, he registered no pressure at all, and that was actually the stronger area of his game, as his run defense saw him consistently blocked away from the point of attack, regardless of who he was running up against.

6. Erik Walden, OLB, Indianapolis Colts

Erik Walden produced another fine case study in pass-rushing futility this week, as he achieved absolutely nothing from a pass-rushing standpoint on 20 snaps going after the QB. Walden also missed as many tackles (one) as he made. The Colts as a team achieved very little production rushing the passer, hurrying Raiders QB Derek Carr just twice in the game—on one of those two snaps, however, they knocked him out of the game, and probably the season.

7. Trevor Siemian, QB, Denver Broncos

Denver doesn’t need Trevor Siemian to be good in order to be successful, but they need him to be a lot better than he was this week against Kansas City. Siemian only threw one interception, but that was due very little to good decision-making, and a lot to rainy conditions making it tough for Chiefs defenders to bring in passes repeatedly thrown their way. Siemian had three dropped interceptions in the game, and despite that break, ended up with a passer rating of just 43.6.

8. Matt Barkley, QB, Chicago Bears

The Matt Barkley hype train came skidding off the rails in spectacular fashion in Week 16, and buried itself into a mountainside with this performance. Barkley’s touchdown-to-interception ratio this year has always been a little harsh on his performance, given the play of his receivers, but this week, it was entirely fair, as he threw five picks. There was the occasional flash of nice play, but this was the poor game that he had previously avoided in his run of starting games this year, and probably removes any shot he had at fighting for a starting spot in 2017.

9. John Theus, T, San Francisco 49ers

This was about as badly as you will see a tackle beaten in the run game. John Theus was beaten for eight clean tackles when run blocking, and that doesn’t count the plays where he was beaten only for his man to chase the back into somebody else’s arms. Whether it was against William Hayes on the edge, or when trying to down-block Aaron Donald, this was just beyond the capability of Theus to execute.

10. Bobby Hart, T, New York Giants

Somehow, Bobby Hart escaped Week 16's game without surrendering a sack. In 63 snaps of pass protection, he allowed eight total QB pressures, and was the reason his quarterback hit the ground three times, getting utterly undressed by Eagles defensive end Brandon Graham. Eli Manning’s passer rating when pressured in the game, though, was 10.7, so it’s probably fair to say it still mattered.
