his defense is reducing points and possessions for both the offense and defense because his "bend but don't break" defense allows the opposing offense to churn the clock, which reduces the number of total possessions for both teams, and thereby reduces the number of scoring chances for both team. Hence, it isn't totally surprising that he's keeping teams below 28 points when both teams are only getting 3 possessions in an entire half, like occurred during the USF game.
