Last season, the Pittsburgh Steelers had a rookie and a first-year player as their backups to Le’Veon Bell in the season opener, a running back who had literally only been with the team for about six days prior to that game being played after he stayed away throughout the offseason.
The coaching staff elected to minimize his workload, and one way in which they did that was incorporating rare use of four-receiver sets. In prior years, when they did use four receivers it was out of a 10 personnel package, which means one back and four receivers.
