Trent Richardson thinks this guy was an average running back in losses.

Trent Richardson thinks this guy was an average running back in losses.

Yesterday, I noted that Adrian Peterson is averaging nearly two more yards per rush in losses than wins. He’s also averaging a nearly identical number of rushing yards per game in wins and losses.

As you’re about to see, that’s pretty rare. We all know that wins are correlated with rushing yards, so it should come as no surprise that running backs generally gain more rushing yards in wins than in losses.

I looked at all games, including playoffs, from 1960 to 2011, for all players with at least 3,000 rushing yards over that time period. The table below lists the following information for each player:

— His first year (or 1960, if he played before 1960) and his last year (or 2011, if still active)
— All the franchises he played for (which you can search for in the search box)
— His number of career wins, and his career rush attempts, rushing yards, rushing yards per carry, and rushing yards per game in wins
— His number of career losses, and his career rush attempts, rushing yards, rushing yards per carry, and rushing yards per game in losses

The table is sorted by rushing yards per game in wins. Again, for players like Jim Brown or Peterson, they are included but only their stats from 1960 to 2011 are shown. The table only shows the top 50 players, but the search feature works for the entire table, which includes 281 players. In addition, you can click on the drop arrow and change the number of rows shown.

As always, the table is fully sortable. If you click twice on the far right column, you see the career leaders in rushing yards per game in losses. You probably aren’t surprised to see Barry Sanders at the top, but the presence of the running back formerly known as Dom Davis up there is a bit surprising. Steven Jackson is one of the few players who have averaged over 70 rushing yards per game in losses, which jives with the sixth post in Football Perspective history. In addition, Jackson (at least through 2011) and LaDainian Tomlinson form an interesting example of Simpson’s Paradox: Jackson has a higher career rushing yards per game average in both wins (93.9 to 89.9) and losses (71.1 to 63.2), while Tomlinson has the higher career average overall (78.6 to 78.3).



Of course, the really cool thing to do with this data is to see the difference in production in wins and losses. Because of space concerns, I couldn’t put all the information I wanted in the above table, hence the need for the next table, which shows the same biographical information and then also displays the player’s career totals (subject to the same caveats) in rushing yards, yards per game, and yards per carry. The next four columns reproduce the information above, showing each player’s yards per carry and yards per game in wins and losses. To make things easier for you, I’ve highlighted the two win columns in light blue and the two loss columns in light red.

The final two columns show the differences in each player’s yards per carry and yards per game in wins and losses. It is sorted by the differential in yards per game.

Gerald Riggs comes in with the most impressive differential in yards per game in losses rather than wins. Part of that is due to Riggs’ final season in Washington, where he rarely carried the ball but the team went 17-2. Still, even during Riggs’ prime, his numbers in wins and losses were pretty similar.

One other interesting note: if you sorted the table in reverse order, you would have noticed that Jim Brown has the largest differential in rushing yards per game in wins versus losses. While part of that is due to Brown’s dominance in wins — he does have the highest average in wins — he ranks “only” 14th in yards per game in losses. His yards per carry average was over a yard lower in losses relative to wins.

This isn’t all that surprising to me, but that’s only because I remember this great post by Jason Lisk. During Brown’s era, the schedules were extremely unbalanced between the two divisions, and Brown played his entire career in a relatively weak division. As a result, if you ignore strength of schedule, the difference between Jim Brown and say, Jim Taylor, appears much larger than it probably was in reality. For what it’s worth, if you throw out Taylor’s final seasons with the Saints, his differentials drop to -0.23 in yards per carry and -20.3 in yards per game. While that wouldn’t vault him to the top of the list, it would place him roughly in the middle, as opposed to where he currently resides. Looking at wins and losses is hardly a perfect proxy for strength of schedule, but at least in Brown’s case, it does seem to reinforce Lisk’s point.
