David Johnson was so good and so versatile that it might take three Cardinals to replace him in the backfield.
With the Cardinals’ star on the shelf for the next several months due to a dislocated wrist, coach Bruce Arians said Wednesday it will likely be a running-back-by-committee approach on offense.
Kerwynn Williams will be the starter, with Andre Ellington expected to spell him and play on third downs. Chris Johnson, who was released before the season, was brought back Tuesday and is also expected to get carries on Sunday against the Colts.
