10U Coaching Help

I'm coaching a 10U boys rec team and they play 7v7, one completed pass before a shot is allowed. This presents some challenges when trying to teach aspects of the game like unsettled offense and fast breaks, as some coaches "game" the rules and simply won't have their players pick up the breaking middle because they haven't caught a pass yet and therefore can't shoot. Similarly, some coaches just teach their players to straight up not cover the guy with the ball if they still need to make a pass and will instead start doubling off ball.

Any thoughts on how to coach around this? I want my players to understand the game and be ready at the next level, but also don't want to lose to other teams pulling this kind of thing.
