First of the season!!

[MN 3 Sport Ref]

Use advantage/disadvantage. Kid is in the lane 3+ seconds and then sets a screen to free a shooter. Advantage call it.

Kid is in lane 3 + seconds recieves ball for lay-up. Advantage call it.

KId gets off rebound and is stifled by defense for 3+ seconds. Reward good defens call it.

Kid is lost on offense and actually hurting his team and doing nothing constructive. No advantage no whistle.

Kid falls to ground and is laying in lane or fails to clear but is working hard. No advantage no whistle.

IMO useing this trian of thought is good officiating. THe 3 second rule is in the book because it is important as far as advantage/disadvantage. Not to be used as an absolute guideline. Just as the amount of contact we judge to be advantage/disadvantage on a shooter or rebounder.
