Week 2 DVOA Ratings | Football Outsiders

by Aaron Schatz

The New England Patriots take the top spot in our DVOA ratings following Sunday’s 43-0 dismantling of the hapless Miami Dolphins. Baltimore drops one spot to number two, a surprising San Francisco ranks third, and Kansas City and Dallas round out the top five.

But right now the bottom is more interesting than the top, because the Miami Dolphins are bad. Boy oh boy, are they bad. You’ve probably seen a number of statistics of how historically bad Miami is: they have the worst point differential after two games since the 1961 Raiders, they’re on pace to break every known record for offensive futility, and so on. Our numbers certainly agree. Miami is the worst team we’ve ever tracked through two games, going back to 1986, and that’s even more remarkable since they are one of only two teams in the bottom dozen to play both games at home.

No team has ever been this bad at the start of the season, but what’s remarkable is how many of the worst 0-2 teams in DVOA history ended up rebounding and having reasonable seasons. The 1989 Steelers went 9-5 over the rest of their games and even won a playoff game. Nine of the previous 11 worst teams after two games ended up finishing 6-10 or better. Not one of these teams finished in last place in DVOA for the season. Miami is a different animal because the Dolphins are clearly tanking — their trade of Minkah Fitzpatrick being just the latest piece of evidence that this year absolutely doesn’t matter to them — but historically, playing this badly over the first two weeks does not guarantee a team will be the league’s worst for the whole season.

Here’s a look at the worst dozen teams in DVOA since 1986. Remember, there are no opponent adjustments after two weeks for any of these ratings:

Worst DVOA as of Week 2, 1986-2019
2019 MIA 0-2 -114.7% 102-10 2
2001 WAS 0-2 -107.8% 67-3 8-8 -0.5% 17 0
1999 CLE 0-2 -103.5% 69-9 2-14 -39.7% 30 1
2008 STL 0-2 -103.3% 79-16 2-14 -47.1% 31 1
1989 PIT 0-2 -100.5% 92-10 9-7 -8.7% 18 1
1997 SEA 0-2 -95.5% 76-17 8-8 -10.7% 21 2
2018 BUF 0-2 -94.0% 78-23 6-10 -18.2% 28 1
1996 TB 0-2 -91.7% 55-9 6-10 -9.4% 20 1
2005 MIN 0-2 -89.3% 61-21 9-7 -18.5% 25 1
2003 CHI 0-2 -88.3% 73-20 7-9 -14.7% 26 0
2007 NO 0-2 -86.7% 72-24 7-9 -9.7% 22 0
2011 KC 0-2 -85.2% 89-10 7-9 -16.9% 26 1

That 2001 Redskins team, the previous record-holder by DVOA for an 0-2 team, was a little nuts. They continued to get crushed in their next two games, eventually losing five straight although the fifth one was a close 9-7 loss to Dallas. Four of those five games were on the road. Then they turned around and won five straight, with the first games at home but the last two on the road. That put them at 5-5. But they lost three of their last four home games, and ended up 8-8. It was a very strange season.

The Dolphins aren’t just bad on one side of the ball. They’re all-around awful! The Dolphins rank among the dozen worst teams ever through two games on both sides of the ball. Here’s a look at those teams along with where they ended up ranked at the end of the year.

Worst Offensive DVOA as of Week 2, 1986-2019
2002 HOU 1-1 -87.8% 32 32
2001 WAS 0-2 -78.2% 31 26
1989 PIT 0-2 -77.7% 28 24
2006 OAK 0-2 -76.9% 32 32
2019 MIA 0-2 -73.3% 32
2005 MIN 0-2 -70.5% 32 26
1990 NO 0-2 -68.4% 28 23
2013 JAX 0-2 -67.6% 32 32
1999 CLE 0-2 -63.0% 31 26
1996 TB 0-2 -61.5% 30 27
1997 SF 1-1 -61.1% 30 10
2017 CIN 0-2 -60.0% 32 22

How about the fact that the team with the worst-ever offensive rating through two games actually won one of those games? Houston won its first game as a franchise, 19-10 over Dallas. David Carr had just 145 passing yards but over half of them came on two touchdown passes including one of 65 yards. Houston also ran 35 times for 87 yards. The next week against San Diego, Carr went 6-for-25 with 87 yards and took nine sacks with three turnovers.

Miami doesn’t rank quite as badly on the defensive side of the ball…

Worst Defensive DVOA as of Week 2, 1986-2019
1997 SEA 0-2 59.4% 30 19
2006 HOU 0-2 54.3% 32 31
2008 DET 0-2 52.6% 32 32
2008 STL 0-2 52.6% 31 30
2013 WAS 0-2 51.3% 32 21
2007 NYG 0-2 50.9% 32 13
2017 NE 1-1 49.6% 32 31
2017 NO 0-2 48.6% 31 8
2015 CHI 0-2 48.1% 32 31
2012 CIN 1-1 47.3% 32 10
2007 NO 0-2 44.1% 31 30
2019 MIA 2-0 42.6% 32

Interesting that most of the worst defensive DVOA ratings of early season have come since 2000. Remember, like all DVOA ratings, these are normalized for the offensive environment of each season.

What’s remarkable is that it could be worse for the Miami Dolphins depending on how we treat certain plays. We did not penalize Josh Rosen’s interception on the final play of the game, because it was the final play of a 43-0 game and Rosen had nothing to lose by throwing the pass. We generally don’t penalize turnovers on the final play unless they affect the score. But this was a red zone interception. DVOA does lower the strength of plays when two teams are separated by 21-0 to try to account for prevent defenses, but it doesn’t have a “prevent defense” adjustment once a team gets inside the red zone. And red zone interceptions have a higher penalty than interceptions on the rest of the field. So if we treated this as we do most red zone interceptions, Miami’s offensive DVOA rating would drop from -73.3% to -85.4%, the second-lowest offensive rating ever through two games. And Miami’s total DVOA through two games would be a horrific -126.8%.

Let’s flip it around and look at the Patriots. New England is not quite as historically great as the Dolphins are bad, but the Patriots are certainly up there. (It would help if Stephen Gostkowski had not missed a field goal and two extra points so far.)

Best DVOA as of Week 2, 1986-2019
2005 PIT 2-0 111.5% 61-14 11-5 27.2% 4 1 Won SB
1990 CHI 2-0 101.3% 48-13 11-5 15.0% 9 1 Lost Div
1996 GB 2-0 94.4% 73-16 13-3 42.0% 1 1 Won SB
2007 NE 2-0 93.5% 76-28 16-0 52.9% 1 1 Lost SB
1996 SF 2-0 87.8% 61-11 12-4 29.3% 2 2 Lost Div
2002 SD 2-0 85.9% 58-9 8-8 -2.4% 21 1 None
2015 ARI 2-0 85.2% 79-42 13-3 27.4% 3 1 Lost NFC-CG
2019 NE 2-0 83.3% 76-3 1
1989 CLE1 2-0 83.3% 89-24 9-6-1 24.4% 2 1 Lost AFC-CG
1999 PIT 2-0 77.7% 66-20 6-10 1.4% 20 0 None
2007 PIT 2-0 75.6% 60-10 10-6 19.4% 6 1 Lost WC
1996 SD 2-0 74.8% 56-21 8-8 -0.5% 18 2 None

It looks like more of these extreme fast-starters had good seasons than the extreme slow-starters had bad seasons. It’s interesting that only two of these teams had both games at home, the same number as the 12 worst 0-2 starts in DVOA history. And what was in the water in 1996, when three teams had historically strong starts in their first two games? (None of them played mutual opponents.)

The Patriots would move up to 91.3% if we counted the final Josh Rosen interception.

Unlike the Dolphins, New England is not in the all-time top 12 through Week 2 in both offense and defense. No team from 2019 is in the all-time top 12 on offense, though the Dallas Cowboys would be 14th at 53.1%. The Patriots are on the list for the best defensive starts. Other than the 2002 Chargers, these teams all ended the year with very good defenses:

Best Defensive DVOA as of Week 2, 1986-2019
2017 BAL 2-0 -70.8% 1 3
1989 CLE1 2-0 -69.5% 1 3
2006 BAL 2-0 -68.7% 1 1
2002 SD 2-0 -64.5% 1 22
2008 BAL 1-0 -60.8% 1 2
2012 HOU 2-0 -60.1% 1 4
2019 NE 2-0 -55.3% 1
2005 TB 2-0 -54.5% 1 8
1999 TB 1-1 -54.1% 1 2
1988 LARM 2-0 -54.0% 1 5
1991 PHI 1-1 -52.8% 1 1
1996 DEN 2-0 -52.6% 1 3

The extremes of the Patriots and the Dolphins lead to all kinds of fun in our playoff odds simulation. In 30,000 simulations, the Patriots go 16-0 595 times (2.0%) and the Dolphins go 0-16 1,152 times (3.8%). In 29 of 30,000 simulations, both of those things happen (0.1%).

In none of our simulations do the 0-15 Dolphins beat the 15-0 Patriots in Week 17, although it would certainly come up if we did more simulations.

Remarkably, the Patriots only win the Super Bowl in 37% of simulations where they go 16-0 in the regular season. Fans generally underestimate the chances that a great regular-season team will lose in the playoffs, usually to another great regular-season team. It’s not just the Patriots; there are 105 simulations where the Kansas City Chiefs go 16-0 (0.35%) and the Chiefs only win the Super Bowl in 22% of those simulations.

The other big story this week is change at the quarterback position, mostly (although not entirely) due to injuries. I’ve had to totally re-do the offensive projections used in our DAVE ratings. So many teams now have lower offensive projections because of quarterback changes that I had to re-normalize the rest of the league so that the league averages 0%. So every other team now has a slightly higher projection as part of their DAVE ratings.

I’ll note here that every team changing quarterbacks takes a hit in the DAVE ratings. That includes the New York Giants, even though they are changing quarterbacks of their own volition instead of due to injury. Yes, Eli Manning is currently 19th in passing DVOA, right around replacement level at -11.9%. But Manning was only slightly below average last season, and that’s more evidence than just two games of this year. Daniel Jones is a rookie, and a rookie without a very high QBASE, and those rookies tend to struggle. And we know that preseason performance has no value as far as forecasting Jones’ performance during the regular season, even if he clearly did look better than Manning. So until we get more evidence that shows that Jones is an upgrade, our DAVE ratings will have to move the New York Giants down.

For the Giants and the Pittsburgh Steelers, we can now assume that Jones and Mason Rudolph will be the new quarterbacks for the rest of the season. That’s not the case with three other teams: Jacksonville, New Orleans, and the New York Jets. Sam Darnold is supposed to be back in a month, and Nick Foles and Drew Brees should be able to return around midseason. This brings up a problem with the DAVE ratings. How should I be displaying them? Based on the current quarterbacks, or based on what the projections estimate that the end-of-season ratings should be for these teams based on how much we expect each quarterback to play?

I asked this question on Twitter, and the latter choice won narrowly in the voting, so this is how I have displayed the DAVE ratings this week. The DAVE ratings are an estimate of what we can expect the team’s offensive DVOA to be for the rest of the season. For New Orleans, for example, the rest of the season includes half a season of Drew Brees rather than Teddy Bridgewater. I’m going to have to do a little bit more work to make sure I’m estimating things right in future weeks, once we’ve got multiple quarterbacks mixed into the current-season DVOA of each team. But here’s a look at how I’ve figured these ratings as of this week:

  • For Jacksonville, I assumed Gardner Minshew would play half the remainder of the season and Nick Foles the other half. If you want the team’s DAVE specifically for this week with Minshew, subtract 3.2%.
  • For New Orleans, I assumed Teddy Bridgewater would play half the remainder of the season and Drew Brees the other half. If you want the team’s DAVE specifically for this week with Bridgewater, subtract 6.0%.
  • For the New York Giants, DAVE drops by 7.6% with Daniel Jones at quarterback.
  • For the New York Jets, I assumed Luke Falk would play one-third of the season and Sam Darnold two-thirds. If you want the team’s DAVE specifically for this week with Falk, subtract 13.3%.
  • For Pittsburgh, DAVE drops by 10.3% with Mason Rudolph at quarterback. 

These changes have also been accounted for in the playoff odds simulation, although for that simulation I can make things a little more random. (For example, there’s a 20 percent chance of Darnold returning each week between Week 5 and Week 9.)

These are the Football Outsiders team efficiency ratings through two weeks of 2019, 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. As always, positive numbers represent more points so DEFENSE is better when it is NEGATIVE.

Please note that there are no opponent adjustments in DVOA until after Week 4. (It’s still listed as DVOA instead of VOA because I don’t feel like going through and changing all the tables manually.) In addition, our second weekly table which includes schedule strength, variation, and Estimated Wins will appear beginning after Week 4.

DAVE is a formula which combines our preseason projection with current DVOA to get a more accurate forecast of how a team will play the rest of the season. Right now, the preseason projection makes up 80 percent of DAVE.

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>
