The Mavericks team owner was angry with a decision that went against his team in its four-point loss to the Hawks. As he tweeted through the rage, he touched on what he considers the biggest problem with officiating: bad supervisors.

McCutchen has been the league’s vice president, head of referee development and training since December 2017.

The officiating crew for Mavs-Hawks on Saturday was Rodney Mott, Derrick Collins and Matt Myers. They called 22 fouls on the Mavs and 21 on the Hawks. Free throws were 26-19 in favor of host Atlanta. Those aren’t the facts that Cuban is complaining about, however.

His main complaint was with how the crew handled a late goaltending call that became a basket after a whistle.

That’s why he began his thread with this salvo:

Cuban won’t get any satisfaction from the NBA over that sequence; he will instead get a hefty fine from it. Cuban, of course, is willing and more than able to pay for the privilege of going nuclear after feeling wronged — and of making a larger point about improving referee development.
