The Nets Media Guide Preserves the Full Package
The clearest package source is the New Jersey Nets' historical media guide. It records that New York obtained Mike Bantom from Seattle on January 27, 1977 in exchange for the Nets' 1979 fourth-round pick, which became James Donaldson, plus cash. Pro Sports Transactions preserves the same media-guide account while flagging conflicting historical descriptions. Basketball-Reference's team and league ledgers record New York selling the rights attached to Donaldson to Seattle on that date, and Bantom's player ledger records Seattle selling his rights to New York. Taken together, the sources support the canonical Bantom-for-pick-and-cash package while explaining why individual ledgers describe the two sides as sales.
Bantom Was Excellent for 33 Nets Games
Bantom played 33 games for New York after the transaction. He totaled 614 points and 285 rebounds, which works out to 18.6 points and 8.6 rebounds per game, while logging 33.8 minutes. That was strong immediate production for a Nets team going through a difficult first NBA season.
The Nets Did Not Keep Him Beyond the Season
Bantom became a veteran free agent after the season and signed with Buffalo on September 1, 1977. New Jersey received a future fourth-round pick as compensation. Because the primary compensation ledger used here does not identify the eventual selection, this review credits the Nets with the existence of that downstream draft asset without inventing a player outcome.
The Fourth-Round Pick Became James Donaldson
Seattle's incoming 1979 fourth-round pick landed at No. 73 and became James Donaldson. Donaldson spent 1979-80 playing professionally in Italy before joining the SuperSonics in 1980-81. He appeared in 68 games as a rookie, then played all 82 games in both 1981-82 and 1982-83. Across those three Seattle seasons he logged 232 regular-season games.
Donaldson Became a Useful Seattle Center
His role grew each year. Donaldson averaged 5.3 points and 4.5 rebounds in 1980-81, 8.1 points and 6.0 rebounds in 1981-82, then 8.9 points and 6.1 rebounds in 1982-83. The late fourth-round pick therefore became a durable rotation center rather than a player who never reached the roster.
He Also Retained Downstream Trade Value
In August 1983 Seattle included Donaldson, Greg Kelser, Mark Radford and two draft picks in the trade that brought back Tom Chambers, Al Wood and additional picks from San Diego. Donaldson's inclusion demonstrates continued transaction value, but this review does not assign the full Chambers return to him because the package contained several other substantial assets.
Final Verdict
Sonics Win, A-/B. Seattle receives an A- because a fourth-round pick plus cash cost produced 232 games from Donaldson and preserved later trade utility. New York receives a B because Bantom was highly productive in 33 games and his free-agent departure generated another draft asset, but the Nets did not retain his services beyond that season. The source record is unusually messy, so the package explanation explicitly distinguishes the Nets media-guide account from the Basketball-Reference rights-sale presentation. Confidence is high on the player movement and pick identity and medium-high on the exact package mechanics.
