The February 1 Trade Is Straightforward
Basketball-Reference's Kansas City-Omaha, New Orleans and NBA league transaction ledgers agree on the February 1, 1975 exchange. The Kings sent Nate Williams to the Jazz and received Rick Adelman plus Ollie Johnson. No draft choice or cash belongs to the original transaction, which makes the first stage of the comparison unusually direct. The historical team keys in the archive map Kansas City-Omaha to the modern Sacramento Kings franchise and New Orleans to the modern Utah Jazz franchise, but the analysis preserves the contemporary team names when describing what happened.
Adelman Was a Short-Term Piece
Rick Adelman had just arrived in New Orleans from Chicago in November 1974. After moving to Kansas City-Omaha, he appeared in 18 regular-season games and averaged 6.7 minutes and 1.7 points. Those were the final NBA games of his playing career. Adelman later became far more important as an NBA coach, but that coaching career cannot be credited to this player transaction. For trade-value purposes, the Kings received only the 18 games he actually played after the deal.
Ollie Johnson Supplied the Real Kings Return
Ollie Johnson was the durable piece. He played 30 games for Kansas City-Omaha after the trade in 1974-75, then 81 games in 1975-76 and another 81 in 1976-77. That is 192 regular-season games for the franchise, including a 1975-76 season in which he averaged 10.1 points and 4.4 rebounds in 26.2 minutes. Combined with Adelman's 18 games, the Kings received 210 regular-season appearances from the two incoming players. Johnson was a legitimate multi-year rotation forward and keeps the Kings side from being graded as a poor outcome.
Johnson Still Had Trade Value in 1977
On June 1, 1977, Kansas City sent Johnson, a 1978 first-round pick and a 1978 second-round pick to the Lakers for Lucius Allen. That later move shows Johnson retained value, but the full Allen return cannot responsibly be assigned to Johnson because two draft picks were also in the package. A source-backed archive should record the continuing asset chain without pretending one component purchased the entire downstream player. The original deal therefore gets credit for Johnson's direct Kings production and only limited qualitative credit for his later inclusion in a larger trade.
Williams Became the Best Player in the Deal
Nate Williams immediately took on a larger scoring role in New Orleans. He played 35 games after the trade in 1974-75 and averaged 14.3 points, then appeared in 81 games in 1975-76 at 12.8 points and 79 games in 1976-77 at 12.3 points. He added 27 more Jazz games in 1977-78 before being traded. Across those four partial seasons, Williams played 222 regular-season games for New Orleans. His scoring role and durability made him the strongest directly attributable basketball asset on either side of the transaction.
New Orleans Also Preserved Downstream Value
The Jazz did not simply lose Williams when his role ended. On January 5, 1978, New Orleans traded him to Golden State for a 1978 second-round pick that became No. 35 Tommie Green. Green did not become a meaningful NBA player for the Jazz, so the later pick did not add major realized production. It still matters that Williams remained tradeable after 222 games. New Orleans received both the best direct player outcome and an additional asset at the end of the tenure.
Final Verdict
Jazz Win, A/B+. New Orleans receives an A because Williams gave the franchise 222 regular-season games, three consecutive double-figure scoring seasons after the trade and a later second-round pick. Kansas City receives a B+ because Johnson supplied 192 useful games and Adelman added 18 more, but the combined package never matched Williams' offensive role or downstream value. The Kings side was productive enough that this is not a lopsided deal; the Jazz simply received the best player and kept value alive longer. Confidence is high on the date, package, direct production and downstream transactions. The verdict reflects only verified transaction terms and realized team value.
