One youth parochial league I worked had a 15 point no press rule. Team leading by 15 or more cannot press full-court, only half-court. An age group or two within that leage bans full-court pressing until the 4th quarter, unless the 15-point margin is in effect.

Another youth organizational league I worked has a similar no press rule, only the team that leads by 15 or more must contain their defense within the 3-point line. They cannot even reach over the line to slap the ball away or the like.

Pros: Gives the trailing team an opportunity to run their offense without giving up the ball before setting up. Lets the kids play ball without getting their self-esteem shot to hell.

Cons: Gotta remember which league I'm working, and which age group within the parochial league. Headache after 3 or 4 games on one Saturday afternoon after trying to enforce these rules.

One note I might add is that despite the 15 point no-press rule, I still see some unheavenly blowouts (these leagues are either church schools or church youth organizations leages) that would shame some high school varsity teams.
