Handiman has an EXCELLENT question, except that he's too spacey to word it right. His real question is,
Okay, okay, so the OFFICIAL excuse for disallowing Sabonis in the 1985 draft was that he was under 21 on Draft Day. I'm asking, how does that make SENSE, not, whether it is the OFFICIAL excuse. It is INCONSISTENT with history. Why has that supposed rule not been enforced on other draftees?
----------------
Limitations of Basketball-Reference: 1) It will only find it by age on Feb. 1 of their rookie seasons. (Sabonis was 21 by then.) 2) It will only find this for those who played, not those who were drafted, so the list is really longer.
Limitation I added: Only search up to the watershed year of 1995. (That's when Kevin Garnett started the modern influx of high schoolers drafted directly into the NBA.)
Preliminary result: 142 players played (not just, were drafted) at age 21 or younger, before 1995.

Method: Then you check each player individually to find who was under 21 on Draft Day.
I only checked Sabonis's own 1985 draft. (I leave all other years to You the Reader as homework.) Benoit Benjamin was 1 month older than him, Kenny Green 2 months older, and Pete Williams 3 months younger. All were drafted in 1985 when younger than 21, and played in 1985-86.
Conclusion: The official excuse is a lie.
If there was a higher age for foreign players than American college players, then the official excuse should include that information instead of simply saying, "Sabonis was disallowed because he was under 21." Besides, the age requirement for foreign pros usually goes the other way with a lower, not higher, age.
Does a list of official 1985 draft rules exist, including this age rule? Or does the media just report later that there was a mystery rule, to justify what Stern already did?
