Last postseason, the spotlight was all over Golden State Warriors‘ forward Draymond Green. Green was seen, on multiple occasions throughout the playoffs, flailing his body parts, specifically his legs, and often times connecting with opponents below the belt. Eventually, that caught up to him as the NBA suspended him for a groin hit on LeBron James in the NBA Finals.

After the season, the NBA made some changes to the rules, creating the Draymond Green rule. Here's the description of the new rule.

NBA referees will be cracking down this season on the kind of hits to the groin area that resulted in Draymond Green's suspension during the NBA Finals.

The hits to the groin — termed “unnatural acts” by the league — are a point of emphasis after a number of situations involving Green during the postseason. The All-Star forward had a habit of flailing his arms or legs and a few times made contact with opponents in the groin area.

Joe Borgia, the NBA senior vice president of replay and referee operations, said players are no longer just swinging their arms in attempt to draw a foul when taking a shot.

“Now all of a sudden legs are coming out in different directions at weird times, they're coming higher,” he said. “Well, for the protection of the players, we're going to stop it.”

After potentially costing his team an NBA Championship, it seems like Green may have not learned his lesson yet.

In the preseason finale between the Warriors and Portland Trail Blazers, Green appeared to flail on a shot attempt. On the attempt, he also flung his leg up towards the defending Allen Crabbe.
