Buy Or Sell: Retaining Teryl Austin as defensive coordinator was the wrong move.
Explanation: The Steelers gave up the 12th-most yards in the league last season, but allowed the sixth-fewest points. They ranked in the top 10 in takeaways, but in the back half of nearly everything else but points scored per drive. Their third-down defense was bad; their red-zone defense was good; their quick-change defense was bad; all in all, it was a mixed bag. The man who presided over that unit is back for the next two seasons.

The Steelers defense benefited from playing a bunch of teams at less than 100 percent.
