Bengals player personnel director Duke Tobin said Wednesday that Mixon will act as the team's lead runner in 2018 and will be relied upon heavily, Katherine Terrell of reports. "Joe really came on for us in the later part of the [past] year, second half of the season. He's going to be our bell-cow running back," Tobin said. "We are going to combine him with [Giovani Bernard] and we really feel good about that position group." As a second-round rookie out of Oklahoma, Mixon saw more limited usage behind starter Jeremy Hill (ankle) during the Bengals' first two games before effectively emerging as the top back on the depth chart for the bulk of the campaign.
