OAKLAND (CBS SF) – The hush-hush firing of Golden State Warriors assistant coach Darren Erman earlier this month appears to have come after he was caught recording a number of private conversations.

When Warriors assistant coach Darren Erman was fired earlier this month, the reason given was a “violation of company policy.” Now ESPN reports that the issue was digital recordings of conversation among staff and players, many without the consent of those being recorded.

“He was taping everything,” one source told ESPN. “Taping pregame speeches wouldn’t have been that bad, but he was taping guys just sitting around talking in the coaches’ office.”

According to the report, Erman was not even in the room as some of the recordings were made.

Erman was the second member of coach Mark Jackson’s staff to be removed in the closing weeks of the regular season Head Coach Mark Jackson reassigned assistant Brian Scalabrine to the team’s NBA Development League affiliate in Santa Cruz on March 25 because of what Jackson called a “difference in philosophies.”

Erman was in his third season with the Warriors after spending four years with the Boston Celtics, where he worked under Doc Rivers. He also coached the Warriors’ summer league championship team in Las Vegas last year and spent most of his time during the season reviewing video and studying opponents.

Yahoo Sports reports that Erman has been re-hired by the Celtics.
