The closest I found was the Islanders in '82. Hector Marini was traded to NJ 10/1/82, their roster for '82-83 was the same as the previous season with 25 players remaining with the team and no changes throughout the lineup with the exception to Neil Hawrylil who played one game in '81-82, the only 'new' players that played the upcoming season were Kevin Devine (2 games) and Darcy Regier (6 games), who was part of a trade in 1978, and Mats Hallin (30 games).The goalies (Smith+Melanson) stayed the same, as did the defense (Potvin, Jonsson, Langevin, Morrow, Persson, Dineen, Lane, McEwen, Boutilier) and offense (Bossy, Trottier, Tonelli, Bourne, Gillies, B. Sutter, Goring, D. Sutter, Nystrom, Gilbert, Merrick, Kallur, and Carroll. Nothing much changed besides Hallin (free agent signing) and the minutes played.
