5 greatest Cowboys one-hit wonder seasons in franchise history

4. Greg Hardy, DE (2015)

Although Greg Hardy is somewhat of a controversial player and pick for this particular category, there's no denying the impact he made when he was able to stay on the field as an NFL player.

The former sixth-round pick out of Ole Miss played just one season with the Dallas Cowboys, racking up 6.0 sacks, 20 QB hits, 9 TFL, an interception, and a forced fumble. He may not have played at the All-Pro level he reached while he was a member of the Carolina Panthers, but he led the Cowboys in QB hits that season by a longshot.

Even if most of his production came early in the 2015 season, it was still a strong season for Hardy, who was not brought back after the season due to off-field issues.

Hardy has since become a professional MMA fighter and professional boxer.

3. Robert Quinn, DE (2019)

Robert Quinn played just 14 games for the Dallas Cowboys in the 2019 season, but it was a productive season for him. He racked up 11.5 total sacks that season, 35 total pressures, 22 QB hits, and 13 TFL to go along with two forced fumbles.

The former first-round pick out of North Carolina was one of the NFL's most underrated pass rushers for a really long time, and his one year in Dallas is easily forgotten given how good he had been at times before that as a member of the Rams and after as a member of the Chicago Bears.
