By the time we get to Week 16, movement in the DVOA ratings is not necessarily going to lead to movement in the DVOA rankings. That's the case this week, as the Los Angeles Rams drop slightly from 38.0% to 36.0% but remain in the top spot in both full-season and weighted DVOA. We're still watching to see if they can become just the sixth team in DVOA history to finish the year in the top five for all three phases of the game. This week, the Rams' offensive DVOA climbed back into the top five, and their defensive DVOA dropped slightly to fall out of the top five.

New Orleans stays steady at No. 2 this week -- rounded to a tenth of a percent, their DVOA is the same as it was a week ago. In the rest of the top ten, we see Pittsburgh, Minnesota, and New England move up while Philadelphia, Baltimore, and Jacksonville move down.

Pittsburgh moves up two spots to No. 3 after the best single performance any team has had this year, with 106.4% DVOA. Now, of course, that's slightly affected by the fact that the Houston opponent adjustments are a little wonky, incorporating six games of Deshaun Watson and nine games of much worse quarterbacks. But still, that 34-6 win was a Christmas ass-whippin'. So much for Pittsburgh's problems playing down to bad teams on the road.

Week 16 brought us the best single game of the season for both of the AFC's top teams. The Patriots had 64.4% for their win over Buffalo, narrowly ahead of 61.4% from Week 10's win in Denver. The Patriots' win probably didn't seem quite that good, for many reasons: the overturned Kelvin Benjamin touchdown, the pick-six that doesn't hurt DVOA as much as it hurts a team's chances of winning the game, and the fact the Patriots turned on the afterburners and ran away after halftime. They were especially good in the fourth quarter. On offense, the Patriots went from 30.2% DVOA through the third quarter to 122.4% DVOA in the fourth quarter, averaging 7.9 yards and getting at least half the needed yards on 14 of 17 plays. On defense, the Patriots went from 12.8% DVOA through the third quarter to -62.3% DVOA in the fourth quarter, allowing just 1.9 yards per play with more than five yards on just two of 16 plays and a forced fumble that the Bills recovered.

Combine this Patriots performance with Nick Foles' disaster against Oakland and Cam Newton's mostly poor day against Tampa Bay, and we end up with the weird result that the Patriots improved their DVOA in all three phases of the game this week but also fell back into last place on defense. With a week to go, they are once again first in offense and last in defense. This truly has been a year without any really bad defenses, while the best defenses have struggled in recent weeks. Only the Jaguars' pass defense has been truly great all year, and even they can't be called a great defense overall because of struggles against the run. The Ravens are now the No. 1 defense at -16.7%, but 29 of the 31 teams to lead the league in defensive DVOA since 1986 were better than that. (The exceptions were the 2001 Eagles and 2007 Titans.) The Patriots' last-place defensive DVOA of 12.0% would stand as the best rating ever for a defense that finished in last place.

Both the Patriots and last week's last-place defense, Oakland, have improved significantly in the last couple months and now have a big gap between full-season DVOA and weighted DVOA. The Patriots are dead last in defensive DVOA but 22nd in weighted defense. The Raiders are now 28th in defensive DVOA for the full season but 16th in weighted DVOA. Some teams have gotten worse, as well. Buffalo, Cincinnati, Detroit, and Houston are all at least eight spots lower in weighted defensive DVOA than they are in full-season defensive DVOA.

One nice thing this season is that there aren't any particularly good teams that are going to miss the playoffs. The top 10 teams in DVOA right now are all either in the playoffs or very likely to make it (Baltimore). If the Los Angeles Chargers make the second AFC wild card, that will be 11 of the top 11 teams in DVOA. The second NFC wild card will likely also have an above-average DVOA; Seattle is effectively tied for 13th, and while Atlanta is 17th, the Falcons would probably move up with a win over the Panthers. That leaves Tennessee and Buffalo as the only teams with a negative DVOA still eligible for the postseason, and even they aren't that bad. Tennessee is No. 19 and Buffalo is No. 20, although they do a lot worse in weighted DVOA: No. 22 for Tennessee and No. 28 (yikes) for Buffalo.

As noted above, Jacksonville's poor performance against Jimmy Garoppolo and the 49ers has dropped the Jaguars out of the top spot in defensive DVOA. (That's covered in Any Given Sunday this week, and will also be the subject of Thursday's Film Room.) In last week's ESPN Insider "experts pick" piece, I chose that game as my upset of the week based on the idea that Jacksonville has been the league's most inconsistent team this year. I know some people were curious what I meant by that. We measure week-to-week consistency with a simple Excel function called variance. It's honestly not complicated math: I just stick every week's DVOA rating for a team into the variance function and get the result. Jacksonville had the highest variance last week and it's even worse this week after they faceplanted against San Francisco. The important part of Jacksonville's inconsistency has been considering opponent strengths. Jacksonville stomped on the two best AFC opponents they had this year, beating Baltimore 44-7 and Pittsburgh 30-9. But they lost by 21 points to the Tennessee Titans, a team in the bottom half of the DVOA ratings despite their winning record. They also lost to losing teams Arizona, the New York Jets, and now San Francisco.

I've got our first 2017 season edition of the famous week-to-week graphs to show you what that kind of inconsistency looks like. I also want to show you how the variance function doesn't necessarily measure inconsistency from each week to the next week specifically. It measures inconsistency over the entire season. To demonstrate, take a look at the team that ranks 31st in variance, the Houston Texans. Houston has not been really up-and-down this season. The Texans simply went from having a good quarterback to not having one. They have five positive games, all with Deshaun Watson starting. The Texans come out high in variance because they have a very high high and a lot of low lows. But their graph looks a lot different from Jacksonville's:

The line of a different color, for those who don't remember from past years, represents a five-week moving average of how well the team is playing.

What kind of team is the opposite of Jacksonville this year? Well, no team in 2017 has consistency to match the 2016 New York Giants, who at 2.5% had the lowest variance of any team in any season since 1986. This year's lowest variance belongs to the Detroit Lions at 4.4%. Map out Detroit's season, and you get a picture of very slow and steady decline.

Jim Caldwell was quoted earlier today saying "there's nothing we excelled at this year," and he's mostly correct. The Lions were a team that was slightly above average in a somewhat boring way until they were slightly below average in a somewhat boring way. They rank 12th passing and 16th in pass defense. At least that's better than the ground game, where the Lions are 30th running the ball and 28th in run defense. However, Caldwell's comment is really unfair to kicker Matt Prater and rookie return man Jamal Agnew, who have the Detroit special teams in the top ten. You aren't going to make the playoffs when the best aspects of the team are punt returns and long field goals, but hey, the Lions did excel at something this year.

This week, there will be no Football Outsiders-branded Powerline players for EA Madden Mobile because the EA offices are closed for the holidays. Next week, in the final regular-season DVOA ratings and commentary for 2017, we'll have our last Powerline players for Madden Mobile as well as our December stars for Madden 18 on consoles.

All stats pages should now be updated through Week 15, including snap counts, playoff odds, and the FO Premium DVOA database. The exception is the drive stats and pace stats, which will not be updated this week because Jim Armstrong is on vacation for the holidays.

These are the Football Outsiders team efficiency ratings through 16 weeks of 2017, measured by our proprietary Defense-adjusted Value Over Average (DVOA) system that breaks down every single play and compares a team's performance to the league average based on situation in order to determine value over average. (Explained further here.)

OFFENSE and DEFENSE DVOA are adjusted to consider all fumbles, kept or lost, as equal value. SPECIAL TEAMS DVOA is adjusted for type of stadium (warm, cold, dome, Denver) and week of season.

WEIGHTED DVOA represents an attempt to figure out how a team is playing right now, as opposed to over the season as a whole, by making recent games more important than earlier games.

To save people some time, please use the following format for all complaints:

<team> is clearly ranked <too high/too low> because <reason unrelated to DVOA>. <subjective ranking system> is way better than this. <unrelated team-supporting or -denigrating comment, preferably with poor spelling and/or chat-acceptable spelling>

ESTIMATED WINS uses a statistic known as "Forest Index" that emphasizes consistency as well as DVOA in the most important specific situations: red zone defense, first quarter offense, and performance in the second half when the score is close. It then projects a number of wins adjusted to a league-average schedule and a league-average rate of recovering fumbles. Teams that have had their bye week are projected as if they had played one game per week.
