Pittsburgh Steelers HC Mike Tomlin purports to adapt to his circumstances, and perhaps he does. Or at least, perhaps he thinks that is what he is doing. When he had Ben Roethlisberger at the peak of his powers, for example, he played much less conservatively. In his latter years, however, and since then, ball security has been of greater value.
One area—literally—that has been a point of contention is the middle of the field. The Steelers under Mike Tomlin have not targeted that area in the passing game as much as some other teams have. The assumption is that you’re more prone to turnovers in that range, so it’s best to be avoided.
