I think there's another angle here, which is that the individual players may have been harmed - with confidential scouting reports or player performance data, the behavior of the Cardinals may have changed towards those players. They may have missed opportunity to advance their careers, or get a better deal, etc.

It's not just about one team spying on another team, there are ripple effects here of people who might have been negatively impacted by the illegal activity of the Cardinals.
