James Conner hasn't played a full, 16-game season as a pro. In fact, Conner averages just 12 games per year in his three seasons with the Steelers, 75 percent of a full season.
Those numbers peaked as a rookie, when Conner was available for 14 games but played just six percent of the team's offensive snaps working behind Le'Veon Bell. He went down late in that season with a knee injury, getting shut down for the team's final two games.
Most recently, in 2019, Conner missed time throughout the season. It wasn't just one injury requiring surgery but rather nagging injuries — to his shoulder, to his thigh — that caused him to miss six games in all.
