Adjusted Points Per Drive

I love drive stats. There’s no better method, in my opinion, of measuring the performance of offensive and defensive units. However, raw points per drive has a couple of glaring flaws – it doesn’t account for field position or adjust for league offensive efficiency. In this post, I am going to correct those issues and rank every offense in the drive stat era (1997-2015). ^[1]Drive Stats provided by Jim Armstrong of Football Outsiders, and expected points data courtesy of Tom McDermott. To accomplish this, I created a simple metric called Adjusted Points Per Drive. Here’s how it’s calculated:

Step 1: Calculate total offensive points for each team. OffPts = PassTD * 7 + RushTD * 7 + FGAtt * (LgFGM / LgFGA). I chose to use the average value of a field goal attempt rather than made field goals, as I want to minimize the effect of special teams. In 2015, for example, the average FGA was worth 2.535 points, so I plug that number into each team’s number of attempts.

Step 2: Calculate points per drive (PPD). All drives ending with a kneel down are discarded. PPD = OffPts / Drives.

Step 3: Adjust for starting field position. The expected points value of each yard line is a bit noisy, so I smoothed it out into a simple linear formula. Every yard is worth 0.05 expected points, and PPD is normalized based on an average starting field position at the 30 yard line. I call this field position adjusted points per drive, or fPPD for short. fPPD = PPD – ((AvgFP – 30) *0.05). With this step, we can accurately compare the scoring production of all teams within a given season.

Step 4: Adjust for league scoring efficiency. I normalize each season’s fPPD to a baseline of 1.75 to calculate adjusted points per drive. At the team level, AjPPD = fPPD / LgfPPD * 1.75. Now, at last, we can compare the scoring production of every team since 1997. To make AjPPD more intuitive, I also translate it into adjusted offensive points (AjPts) using a baseline of 180 drives per team season. AjPts = AjPPD * 180.

To get a sense of the scaling, the table below provides per team averages of the PPD derivatives for each season. “Mult” is the multiplier used to normalize the season to 1.75 AjPPD.

Year	OffPts	Drives	AvgFP	PPD	fPPD	Mult
2015	342	180	27.3	1.90	2.04	0.86
2014	337	178.8	27.71	1.88	2.015	0.87
2013	346	185.9	27.87	1.86	1.982	0.88
2012	333	181.3	27.52	1.84	1.972	0.89
2011	329	183.8	28.08	1.79	1.899	0.92
2010	326	182.6	29.82	1.79	1.808	0.97
2009	320	181.4	29.48	1.76	1.804	0.97
2008	325	176.2	30.11	1.84	1.849	0.95
2007	316	180.1	30.61	1.75	1.745	1.00
2006	306	180.8	30.27	1.69	1.692	1.03
2005	309	182.4	31.03	1.69	1.649	1.06
2004	317	183	30.68	1.73	1.718	1.02
2003	307	184	31.47	1.67	1.602	1.09
2002	322	183.1	31.42	1.76	1.699	1.03
2001	297	184.2	31.27	1.61	1.553	1.13
2000	307	184.7	31.39	1.66	1.6	1.09
1999	305	191.2	31.43	1.60	1.529	1.14
1998	313	187	30.61	1.67	1.651	1.06
1997	304	183.4	30.91	1.66	1.626	1.08

We see some interesting patterns emerge from this table. Offensive efficiency has skyrocketed in recent years, but scoring hasn’t increased quickly enough to catch up. Part of that is because teams are getting slightly fewer drive opportunities per season than they did 15 years ago. From 2011-15, teams averaged 182 drives per year, while that number was 186 from 1998-02.

However, the main culprit in the scoring lag is field position. The average starting position of drives has steadily decreased since its peak between 1999-03; there was a sharp dropoff in 2011 when kickoffs were moved to the 35 yard line, but the downward trend really started in 2004. There is a direct correlation between the league’s turnover rate and average field position, which makes sense because turnovers often result in short fields. Kickers have become progressively more adept at turning kickoffs into touchbacks, and increased field goal accuracy has resulted in fewer short fields after missed kicks.

Once we adjust for field position, the league’s offensive evolution becomes clear. Today’s offensives are scoring more often despite a significant field position disadvantage compared to 10 or 15 years ago. Since 2004, league AjPPD has risen steadily, not coincidentally in near perfect lockstep with leaguewide passing efficiency.

Now it’s time for the fun part. This table presents the drive stats of all 601 teams since 1997, sorted by AjPPD. I thought it would be illuminating to compare raw offensive points to adjusted points, hence the “Diff” column. A positive difference means the team looks better after being adjusted for drive count, field position, and league offensive efficiency. The table lists all 601 teams, and is searchable and sortable; for ease of viewing, only twenty teams are currently displayed.

The runaway best offense of the last two decades is the 2007 New England Patriots. Most readers will know that this team with Tom Brady and Randy Moss produced the second highest scoring total in NFL history, but very few are aware that they scored all those points on only 158 drives (second fewest in the league). That’s a remarkable feat, especially when compared to the 2013 Broncos, the only team to outscore the `07 Pats. Those Broncos needed 34 extra drives to score 17 more points, and they did it in a higher scoring environment. After adjustments, the 2007 Patriots outscore the 2013 Broncos by a startling 100 points, which drops Denver’s squad all the way down to 10^th place overall.

Meanwhile, the most underrated offense is, ironically enough, the 2006 Indianapolis Colts. Peyton Manning’s SB team had a measly 148 drives and ranked 30^th in average field position, yet still produced over 400 offensive points. Adjustments give them a 117 point boost and vault them to 4^th place overall. The GSOT Rams check in at 2^nd, 5^th, and 9^th, but in the opposite order most people would guess. The 2000 Rams were significantly more dominant than their 1999 champion counterparts, but hardly anyone remembers the 2000 squad because they were derailed by the league’s worst scoring defense.

At the bottom of the pile we find the 2006 Raiders, “led” by the immortal Andrew Walter (and also Randy Moss, which means he was on the best and worst offenses in modern history!). You know things are dire when JaMarcus Russell’s teams looks good in comparison. But my biggest takeaway from the cellar dwellers is the stunningly consistent ineptitude of the Chicago Bears offenses through the years. Da Bears only cleared league average AjPPD in two of the 19 seasons measured, highlighted by a ghastly 0.84 AjPPD in 2004. As bad as their offenses have been by conventional standards, their true performance has actually been far worse. Chicago has generally been near the top in drive opportunities, including four seasons with 200+ drives. Unbelievably, the Bears have also benefited from the best field position in the league, yet still haven’t been able to score with any regularity. In 2007, Chicago led the league in drives and starting field position (thanks, Devin Hester!), but only mustered the 23^rd highest point total. In this era of constant roster turnover, it’s almost incomprehensible that a specific unit could remain that terrible for almost 20 years. At least Chicago has Cleveland to keep them company in the dark basement of offensive futility; the Browns have also put together only two above average offenses since 1997, but they win the tiebreaker by virtue of not existing for two of those seasons.

I’d love to hear your thoughts!
