A couple of weeks ago, I posted a list of the best rushing teams in 2013 using Adjusted Yards per Carry. That metric, you may recall, is calculated as follows:

Rushing Yards + 20*RushingTDs + 9*RushingFirstDowns

We can use the same formula to grade every team across history. To account for era and quantity (having more above-average rush attempts is better), I calculated each team’s AdjYPC average, subtracted the league-average AdjYPC average, and multiplied that difference by the team’s number of rush attempts.

The top team by this method isn’t even an NFL team: it’s the 1948 San Francisco 49ers. You may recall that the 49ers and Browns staged two epic battles that season, and may have been the best two teams in pro football. That season, San Francisco averaged 6.1 yards per carry and rushed for 35 touchdowns on 600 carries; along with 152 first downs, and the 49ers averaged 9.5 Adjusted yards per Carry. That’s the highest average ever, just narrowly topping the production of the franchise’s Million Dollar Backfield six years later. Joe Perry was on both teams because Joe Perry was the man.

The table below shows the traditional rushing data for the top 200 rushing teams of all time; the VALUE column represents the number of Adjusted Rushing Yards produced above average (i.e., relative to the league average AdjYPC). I’ve also listed the three most prominent rushers on each team.

• The 2013 Eagles had a great rushing attack, but only rank 51st on the list. Much higher was Washington’s running game from two years ago, powered by a pair of rookies. And the 2011 Panthers check in at #5, with three players who rushed for at least 700 yards.

• As always, the table is fully searchable and sortable. You can type in “nyj” to see all the Jets teams, but alas, none crack the top 200. If you type in ‘nyg’ you will find that the Giants make the top 200 in each year from 2005 to 2008. That’s pretty surprising to me. If you type in ‘cle’ you’ll find a host of Jim Brown Browns teams, but also the Leroy Kelly/Ernie Green Browns in the years immediately after Brown’s retirement.

• Type in “Vick” and you’ll see that three of Michael Vick‘s Falcons teams, and three of his Eagles teams, fall in the top 75.

What about the worst 200 rushing teams of all time? It’s pretty easy to create that list, too. Take a look:

The expansion Texans take the #2 spot, and with good reason. That was as pathetic a rushing team as I’ve ever seen, and the ranking here bears that out (Jonathan Wells showed up #3 on this list, too). The 2013 Ravens check in as the 10th worst rushing team of all time, and certainly one of the most surprising. Here’s another weird one:

In 1970, Washington (led by Larry Brown) produced 610 yards of value over average, checking in at #99 on the first table. Then in 1971, Brown and the team produced 517 yards of value below average. In ’72, Brown won the AP NFL MVP award. But in ’73 and ’74, Washington was again one of the worst rushing teams ever. That’s a pretty wild ride.

What sticks out to you from the two tables?
