Watch: Darvin Ham plays tough defense

As Poole rose up for a 27-footer, Jarred Vanderbilt ran over to contest. As did Lakerscoach Darvin Ham, stepping onto the court from the sideline with a raised hand.

Sam Vecenie of The Athletic gave a tongue-in-cheek review of Ham's "help defense."

While it is technically illegal for a coach to set foot on the floor, that's a rule that is also routinely violated and routinely ignored in the NBA. For years, the Miami Heat's coaches made a habit of yelling at shooters taking threes in front of their bench.

This year, the NBA made a new rule -- the so-called "Theo Pinson" rule -- that prevented bench players from stepping on the court or celebrating and standing excessively. But that rule does not apply to coaches.

You rarely see any consequences for a coach stepping onto the court -- unless it's a situation where Jason Kidd sees an opportunity to get a free technical foul.

It is clear why the Lakers respond so well to Ham's defensive coaching. He not only preaches defense, he lives it.
