Milwaukee acquired Lucius Allen and Bob Boozer from Seattle for Zaid Abdul-Aziz and reported cash of $100,000. The Bucks received immediate championship value: Boozer played 80 regular-season games and all 14 playoff games for the 1971 title team, while Allen grew into a productive multi-year guard who averaged 17.6 points and 5.2 assists in 1973-74. Seattle did get real value from Abdul-Aziz, especially his 13.8-point, 11.3-rebound 1971-72 season, so this was not a giveaway. Milwaukee still comes out ahead.
Milwaukee and Seattle completed the deal on September 17, 1970. Basketball-Reference's team transaction logs record Lucius Allen and Bob Boozer going to the Bucks for Zaid Abdul-Aziz and cash. Pro Sports Transactions preserves the same four-part exchange and reports the cash at $100,000. The amount is therefore treated as reported rather than exact, but the player movement itself is well established.
The Bucks received both short-term and longer-term value. Boozer played 80 regular-season games in 1970-71, averaging 9.1 points and 5.4 rebounds, then appeared in all 14 playoff games as Milwaukee won the NBA championship. Allen played 61 games that season and stayed with the Bucks deep into 1974-75. His role expanded quickly: 13.5 points and 4.2 assists per game in 1971-72, 15.5 and 5.3 in 1972-73, then 17.6 and 5.2 in 1973-74. Basketball-Reference credits Allen with 8.2 win shares in that 1973-74 season, when Milwaukee returned to the NBA Finals.
Seattle's side deserves more credit than a one-sided title-team story would suggest. Abdul-Aziz immediately gave the SuperSonics frontcourt production, averaging 10.9 points and 7.7 rebounds in 61 games in 1970-71. He improved in 1971-72 to 13.8 points and 11.3 rebounds in 58 games before Seattle later moved him to Houston in 1972. The reported $100,000 also had real value, even though a cash payment cannot be translated cleanly into on-court production. Seattle therefore received a useful starting-caliber big man plus money rather than an empty return.
The separation comes from Milwaukee combining two forms of value. Boozer supplied immediate rotation minutes on a championship team, while Allen developed into one of the Bucks' primary guards and remained productive across several seasons. Seattle received two useful years from Abdul-Aziz and cash, so the transaction did not cripple the franchise or leave it without a basketball return. But Milwaukee's package contributed to the 1971 title immediately and kept producing through another Finals run in 1974. That combination of championship utility and multi-year guard production outweighs Seattle's return without making the deal a historical fleecing.
Bucks Win, B+/B-. Milwaukee earns a B+ for getting a title-season contributor in Boozer and several productive seasons from Allen at the cost of Abdul-Aziz and reported cash. Seattle receives a B- because Abdul-Aziz was a legitimate rebounder and scorer for two seasons and the cash payment added value, even though the SuperSonics did not receive the same championship or long-term impact. Confidence is high on the player movement and career outcomes; the only meaningful qualifier is that the $100,000 figure is reported rather than independently documented as a precise cash ledger.
