The obvious answer to the title is that 3rd down conversion rate should only look at what a team actually did on 3rd down. But nobody actually cares about a team’s 3rd down conversion rate. What people are really talking about when looking at that stat is how often can an offense keep the drive alive for another set of downs.
Below is my attempt at ranking every team by their adjusted 3rd down conversion rate. All I did was simply add a team’s 4th down conversions to their 3rd down conversions, then recalculated their 3rd down conversion rate.
| Team | 3D% | 3D% Rank | Adj3D% | Adj3D% Rank |
|---|---|---|---|---|
| Philadelphia Eagles | 50.0% | 1 | 60.3% | 1 |
| Buffalo Bills | 49.2% | 2 | 53.3% | 2 |
| Dallas Cowboys | 47.2% | 3 | 52.8% | 3 |
| Green Bay Packers | 42.7% | 8 | 50.8% | 4 |
| Los Angeles Chargers | 42.4% | 9 | 50.4% | 5 |
| Minnesota Vikings | 41.5% | 11 | 49.6% | 6 |
| Detroit Lions | 39.7% | 15 | 49.2% | 7 |
| San Francisco 49ers | 44.8% | 5 | 49.0% | 8 |
| Chicago Bears | 43.6% | 7 | 48.9% | 9 |
| Kansas City Chiefs | 45.5% | 4 | 48.2% | 10 |
| Los Angeles Rams | 42.1% | 10 | 47.6% | 11 |
| Baltimore Ravens | 44.1% | 6 | 46.5% | 12 |

| Miami Dolphins | 39.6% | 16 | 44.8% | 16 |
| Indianapolis Colts | 39.2% | 18 | 44.8% | 17 |
| Tampa Bay Buccaneers | 39.5% | 17 | 44.4% | 18 |
| Denver Broncos | 40.5% | 14 | 43.2% | 19 |
| Washington Commanders | 37.2% | 21 | 42.6% | 20 |
| New Orleans Saints | 36.5% | 22 | 41.9% | 21 |
| Las Vegas Raiders | 33.1% | 29 | 41.5% | 22 |
| Cincinnati Bengals | 37.3% | 20 | 40.7% | 23 |
| Arizona Cardinals | 35.7% | 24 | 39.7% | 24 |
| Jacksonville Jaguars | 35.3% | 25 | 38.7% | 25 |
| Pittsburgh Steelers | 36.1% | 23 | 38.5% | 26 |
| Cleveland Browns | 33.8% | 27 | 38.2% | 27 |
| New England Patriots | 34.1% | 26 | 37.9% | 28 |
| New York Giants | 30.5% | 31 | 37.7% | 29 |
| Tennessee Titans | 33.3% | 28 | 37.7% | 30 |
| Seattle Seahawks | 31.5% | 30 | 35.2% | 31 |
| New York Jets | 25.0% | 32 | 30.0% | 32 |
Not too big of a surprise at the top and bottom. The Eagles, Bills, and Cowboys are great at getting a fresh set of downs and the Jets are awful at doing so.
But there are some interesting results in the middle. The Lions for example are only 15th in 3rd down conversion rate, but when you account for how many times they are then able to convert on 4th down, they are 7th in keeping drives alive.
The Chiefs on the other hand are 4th in pure 3rd down conversions, but have only converted 3 4th down attempts all season dropping them to 10th in adjusted 3rd down rate.
But nobody actually cares about a team’s 3rd down conversion rate.
This is where ya lost me bud. It’s a pretty important stat.
because they happen on fourth down, not third down
Why don’t they count 4th on 1st or 2nd down by that logic?
Hey OP do you have the stat for 3rd down conversion on defense?
Pain
I think just quote both numbers and don’t try and combine them and since there is a lot of cuteness that can happen if you do. With 3rd down conversions, people know it’s about how the offense is performing and it’s an offense stat.
But 4th down conversions can be about special teams when the conversion is a result of you not going for it but the opposition being penalised (e.g. roughing the punter, false start on a 4th and 4 etc.)
It’s funny how many people are clowning this, when 3rd and 4th down are regularly presented next to each other
