Boston Bought Arnie Risen from Rochester
Rochester sold Arnie Risen's player rights to Boston on October 26, 1955. Basketball-Reference records Boston acquiring Risen's rights and Rochester selling them on the same date, while the legacy Boston source preserves cash as the consideration. Risen was no ordinary late-career reserve at the time of the deal. He was a four-time All-Star with Rochester, had been a major part of the Royals' 1951 championship team and remained a productive veteran center. Boston was buying experience and interior depth just before the franchise's championship window opened.
Risen Became Three Years of Celtics Center Depth
Risen contributed immediately. He played 68 games in 1955-56, averaging 8.1 points and 8.1 rebounds while logging 1,597 minutes. He returned for 43 games in 1956-57 and 63 in 1957-58, giving Boston 174 regular-season appearances across three seasons. His role became smaller as Bill Russell took over the center position, but Risen remained useful veteran depth and appeared in 10 playoff games during Boston's 1957 championship run. He added another 10 playoff appearances in 1958.
Rochester Received Undisclosed Cash
Rochester received cash, but the reviewed records do not preserve the amount. That consideration was real and may have reflected the Royals' decision to move on from a 31-year-old veteran after seven seasons with the franchise. The basketball opportunity cost, however, is visible. Risen still had three NBA seasons left, remained productive enough to play 174 Boston games and became part of a championship roster. The Royals did not receive a player, pick or identifiable downstream basketball asset in the documented exchange.
A Championship Contributor Makes Boston the Winner
Boston received the stronger realized return. Risen was no longer at his Rochester peak, but three seasons of center depth, 174 regular-season games and a role on the 1957 championship team easily outweigh an undisclosed cash return in the measurable basketball record. The unknown payment keeps Rochester from receiving the lowest possible grade, and the trade should not be confused with Boston's later acquisition of Russell as the primary cause of the dynasty. Still, the Celtics clearly extracted substantial value from a player Rochester sold.
Final Verdict
Celtics Win — Boston A-, Rochester C. Rochester sold Arnie Risen's player rights to the Boston Celtics on October 26, 1955. Basketball-Reference's Rochester, Boston and league transaction logs agree on the transfer, while the legacy Boston intake identifies cash as the consideration. Risen then played three seasons for Boston, appearing in 174 regular-season games and 23 playoff games. He averaged 8.1 points and 8.1 rebounds in 68 games during 1955-56, then remained an important veteran center on Boston's first championship team in 1956-57.
