There is a certain decorum with which a coach in the NBA — and, indeed, a coach in most any major pro sport in the country — is expected to carry himself. Safe to say that, in the last few days, recently departed Nets coach Jason Kidd has violated several of them. Or, at least, the one that matters most.

“I think the one thing you know not to do as a coach is to talk about another job while it is still occupied,” one veteran NBA coach told Sporting News. “You just don’t do that. This is a tough business, there are only 30 jobs and no matter what you think of a guy, every one of us puts his heart and soul into what we do every day. And so you learn to respect your colleagues. But nothing is more disrespectful than gunning for someone’s job while he is still in it.”

What’s worse is that Kidd appears to have done this three times in a matter of days. First, Kidd attempted to usurp the general manager’s role with the Nets from Billy King, having seen Stan Van Gundy get the same broad powers in Detroit and Doc Rivers granted that title with the Clippers. But Brooklyn team ownership, led by Mikhail Prokhorov, had no interest in giving Kidd that level of power.

New Bucks owners Marc Lasry and Wes Edens then came into play for Kidd, receiving permission from the team to speak to him last week — Lasry was a former minority owner with the Nets, and knows Kidd personally.

That’s when Kidd attempted to sell the Bucks on an arrangement by which he would both run and coach the team. Problem is, the Bucks have two people doing those jobs already — coach Larry Drew and general manager John Hammond.

King. Drew. Hammond. That’s three employees Kidd attempted to oust. Kidd eventually came away with the job as Bucks coach, with Milwaukee sending 2015 and 2019 second-rounc picks to the Nets, according to Adrian Wojnarowski of Yahoo! Sports. Drew was never informed of the negotiations with Kidd.

What’s worse, it appears that one of Kidd’s motivations was resentment over the bigger financial packages awarded to Steve Kerr in Golden State and Derek Fisher in New York, each of whom reportedly got five-year, $25 million deals. Both of those coaches, like Kidd, are former players who have never been on a coaching staff before — not only as a head coach, but not even as an assistant.
