First, the Concordian is not violating any privacy law. Privacy would be our only concern in this case. Privacy law is not broken so post the graduation dates. There is no release of names of students, so it does not harm individual status. Posting graduation rates gives athletes another way to compete with one other.
People know how athletes love to compete, on and off field.
Finally this may give coaches an incentive for pushing for a 4-year graduation date. I feel that actually no one would really care to read this posting. I feel there is no real interest to the public, and would not be written. The posting graduation dates does not have any value to the team because there are only so many seniors on the team so it does not prove anything. After the seniors are done playing they usually graduate and leave the school so who cares.
