Basketball is never going to be played perfectly by any team. There are bad shots and 1 v 1 shots taken in today's game w/o a shot clock. That's never going to go away. The question is, which is worse for the game... 4-6 bad shots/game, or 4-6 minutes of no shots/game?
Not all HS teams will run great sets. Very few HS teams have more than 1 or 2 good shooters so you will see packed in mans and zones with emphasis on just the shooters. IMO It has potential to be ugly basketball. I could be wrong, but once it’s implemented it’s not going away
