The Rashard Mendenhall-Andre Ellington Time Share is Unique

by Chase Stuart on November 16, 2013

Ellington races for a long touchdown.

Arizona is one of many teams in the NFL employing a running back by committee philosophy, but no team — now, or at any point in modern history — allocated time quite like the Cardinals. Through nine weeks, Rashard Mendenhall has 105 rushes for 323 yards, giving him a miniscule 3.1 yards per carry average. Mendenhall arrived in the desert this offseason, as part of a reunion with new Cardinals head coach Bruce Arians. The duo worked together for three years in Pittsburgh, where Mendenhall rushed for 3,309 yards and 29 touchdowns and averaged 4.2 yards per carry. But Mendenhall hasn’t been close to the best back added this offseason, as Clemson’s Andre Ellington — a sixth round of the 2013 Draft — has 388 yards this year on 54 carries. Thanks to his spectacular 7.2 yards per carry average, he has outgained Mendenhall despite seeing roughly half as many carries.

How crazy is it for one back in a committee to average more than four more yards per carry than the other back? I ran the following query for every team since 1970:

First, I noted the two running backs who recorded the most carries for each team
Next, I eliminated all running back pairs where the lead back had over 150 more carries than the backup.
I also eliminated all pairings where the lead back was a lead back in name only due to injury to the starter (otherwise, years where Maurice Jones-Drew and Darren McFadden ranked second on their team in carries would be inappropriately included). To do that, I deleted sets where the “lead” back — defined as the back with the most carries — averaged fewer carries per game than the second running back.

After running through those criteria, the table below shows all situations where the backup averaged at least one more yard per rush than the lead back. As always, the table is fully searchable and sortable. It is currently sorted by the difference between the YPC average of the backup and the starter, but you can sort by year to bring the recent instances to the top.

After ten weeks, Ellington is averaging 4.08 more yards per carry than Mendenhall, an obviously unsustainable rate. Over the rest of the 2013 season, Ellington’s yards per carry average will go down, and Mendenhall’s will regress to the mean, too. It’s also possible that Ellington starts getting more carries, and ultimately finishes 2013 with more attempts than Mendenhall (making them ineligible to be on this list). But at least for now, this type of time share would stand out as one of the hardest to justify in NFL history.
