What happened: Jan Volk's notes detail preliminary discussions involving Atlanta, Chicago, Dallas and Golden State. A two-second-round-pick valuation emerged during the Chicago talks, while Golden State rejected a framework presented by Dallas.

Why it matters: The records show negotiations often began with interest lists and valuation anchors rather than formal offers. Boston's roster transition unfolded after Detroit won the 1989 title and as Chicago was rising in the East.

What to watch: Additional archival records could clarify whether any frameworks advanced before the 1990 trade deadline.
