Camp last weekend first experience with "enter on release" since back in the late '70's or so.
Need for tactful preventative officiating reminders not to enter early was same as with old rule. "Enter when legal" was again the phrase that curbed early entry the best.
Just as many early entry violations called as according to the old rule.
No uptick in rough play that I could detect, and I was lookin'.
Entry by players beyond the arc prior to the attempt hitting the rim occurred, not so much to gain an advantage, but because of players' unfamiliarity with the difference in the rule between lane line players and shooter/others.
All in all, didn't make much a difference in any significant way. I did notice lazy and slow lane line players put themselves at more of a disadvantage due to their laziness and slowness, not because of any illegalities on the part of opponents.
