According to a report from the New York Daily News’ Stefan Bondy, Cavs senior director of basketball operations Brock Aller is a candidate for an assistant GM job with the Knicks.
Per Bondy, the Knicks received permission to talk to Aller before the NBA season was suspended and had made an offer with negotiations ongoing. Aller was promoted to his current role in 2017-18 — the same season Koby Altman was promoted to general manager — and has been with the organization since the 2013-14 season. Before that, he spent a decade working directly for Cavs owner Dan Gilbert.
Aller is the Cavs’ capologist, so they’d need to replace him were he to take the Knicks job. But they aren’t going to stop someone from from moving to a more prominent position in another organization. It is notable, though, that someone with a long history with Gilbert and the Cavs might be leaving.
