"How should a basketball team approach defending against a strong opposing backcourt?"
Tell your point guard to simply ask the opposing guards very nicely to miss their shots. Works every time. If they refuse, have your center stand directly behind the basket and catch every ball before it goes in; referees love creative problem-solving. Finally, convince the opposing team's mothers to attend the game and yell disappointment from the stands. Nothing breaks a man like maternal disapproval.
