1958 NBA Trades

Philadelphia traded Phil Rollins to the Cincinnati Royals for Vern Hatton on December 16, 1958. Basketball-Reference's Philadelphia, Cincinnati and league transaction logs all verify the straight player-for-player exchange. Hatton appeared in 42 games for Philadelphia to finish 1958-59, then 67 in 1959-60 and 54 in 1960-61, giving the Warriors 163 games across three seasons. Rollins played 21 Cincinnati games after the trade, 72 the next season and 14 more in 1960-61, totaling 107 games for the Royals. Both sides received rotation value, but Hatton's greater volume gives Philadelphia the stronger realized return.

St. Louis traded Frank Selvy to the New York Knicks on October 22, 1958 for a 1959 second-round draft pick that became Alan Seiden at No. 14 overall. The transaction is preserved in the Knicks' historical media guide, Pro Sports Transactions and RealGM's Selvy timeline even though Basketball-Reference's 1958-59 team and league transaction pages omit it. Selvy then played 68 games for New York in 1958-59, averaging 21.3 minutes and 9.8 points per game. St. Louis used the acquired pick on Seiden, but Basketball-Reference records no NBA regular-season career for him. The verified realized value therefore favors New York.

St. Louis traded the draft rights to Wayne Embry, Jim Palmer, Darrell Floyd, Ken Sidle and Gerry Calvert to the Cincinnati Royals on August 5, 1958 for Clyde Lovellette, who was delivered as the player to be named later in September. Basketball-Reference's league and Ben Kerner executive ledgers place the agreement on August 5, while the St. Louis and Cincinnati team pages record the completed Lovellette transfer on September 16. Lovellette gave the Hawks four strong seasons, 245 games and two All-Star selections. Cincinnati received even more long-term volume from Embry alone: 603 games across eight seasons and five All-Star selections, plus 87 games from Palmer. The verified hindsight result is a high-value trade for both clubs with a slight Royals edge in total longevity.

Detroit acquired Dick Farley and Earl Lloyd from the Syracuse Nationals for cash on June 10, 1958. Basketball-Reference's Detroit, Syracuse and league transaction logs all verify the sale. Farley returned from two seasons of Air Force service and played 70 games for Detroit in 1958-59, averaging 18.3 minutes and 7.0 points. Lloyd became a two-year Pistons regular, playing 72 games in 1958-59 and 68 more in 1959-60 while averaging 8.5 points and 5.7 rebounds across those seasons. Syracuse received legitimate but undisclosed cash, while Detroit received 210 combined regular-season appearances from the two veterans.

On February 16, 1958, Minneapolis acquired Frank Selvy from St. Louis for the rights to Dick Boushka and Terry Rand. Basketball-Reference, the Lakers' official transaction history and both franchise executive ledgers describe an outright trade, while Pro Sports Transactions preserves the older wording that Selvy was loaned to Minneapolis for the rest of 1957-58. That distinction is noted rather than forced: Selvy played 12 Lakers games after the move, totaling 231 minutes and 76 points, while neither Boushka nor Rand ever appeared in an NBA game. The immediate realized value therefore favors Minneapolis, even with uncertainty about whether Selvy's rights reverted to St. Louis after the season.

Minneapolis traded Art Spoelstra to the New York Knicks for Bo Erias and cash on February 5, 1958. Basketball-Reference's Minneapolis, New York and league transaction logs all verify the package. Erias made his NBA debut four days later and played 18 games for the Lakers, averaging 22.3 minutes, 8.2 points, 4.6 rebounds and 1.4 assists. Spoelstra appeared in 17 games for New York at 12.2 minutes, 3.9 points and 3.0 rebounds per game, and those were the final NBA games of his career. With the better on-court return plus cash, Minneapolis received the stronger realized value.

St. Louis traded Dave Plunkett to the Philadelphia Warriors for Walt Davis on January 19, 1958. Basketball-Reference's St. Louis, Philadelphia and league transaction logs all verify the exchange. The legacy TradeVerdicts record called the incoming Hawk 'Buddy Davis'; Basketball-Reference identifies Buddy as the nickname of Walter Francis 'Walt' Davis, so the canonical asset is normalized to Walt Davis. Davis appeared in 26 regular-season games for St. Louis after the trade and nine playoff games during the Hawks' 1958 championship run. Plunkett's Basketball-Reference career ends before a Philadelphia season appears, leaving St. Louis with the only documented post-trade NBA value.
