Another year in the playoffs, the intensity of the game was much higher than that of the regular season, and the discussion about the referee’s penalty also increased. Among them, the topic of “mobile cover” was the most enthusiastic.
Today, let’s talk about this hot topic from the perspective of rules.

The definition of “cover” in NBA rules manual is as follows:
“Cover, when a player does not use inappropriate actions, A screen is the legal action of a player who, without causing undue contact, delays or prevents an opponent from reaching a desired position.).”
Through definition, we can know that there is no requirement for “no movement” in the definition of cover by NBA rules, as long as there is no inappropriate action.

Joe Borgia, chairman of NBA referee & playback Center, said in the popular science video of rules: “The rules do not require the cover person to stand firm or completely still, the cover person can move slightly to maintain stability & absorb confrontation (firm up and absorb contact), but this movement cannot be used to hit the opponent.”
Through the official information above, we can know that it can really move when covering.
