I am maybe OK with the new charge/block rule, but I hate the cylinder rule. They got it wrong against Tre. It's a pure judgement call. They need to make it either a reviewable call, or make it like a kicked ball call - side out with a fresh 20 seconds. You can't make a judgement foul call for someone not even touching the ball handler.
The cylinder rule has been called this way the better part of a decade. And for the record, like it or not, they got it right against Tre.
For reference:
Rule 4, Section 39, Article 1c. The space that a player may legally occupy is defined by an imaginary cylinder surrounding the player and which extends from the floor to as far above the player as he can jump or extend his arms and body. The diameter of the cylinder shall not extend beyond the hands/arms on the front (the arms bent at the elbow), the buttocks on the back and the legs on the sides. These dimensions may vary according to the height and size of the player.
Rule 4, Section 39, Article 1k. The offensive player must be allowed enough space to make a normal basketball play. The defense may not invade the vertical space of the offense and make illegal contact when the offensive player is attempting a normal basketball play. A normal basketball play in this context includes shooting, passing, dribbling or pivoting.
