Will the Pittsburgh Steelers do anything about their below average p defense?

First of all, the p defense is not below average. Given that teams were forced to p more because of a stingy #1 run defense, i'd say their #12 p defense was pretty good. I actually think the Steelers p defense will get worse. Ike Taylor seems ready to leave Pittsburgh for a bigger payday. They drafted a couple of mid-round DBs but they'll take time to adjust. Its not in the teams nature to overspend on a guy like Asomugha or bring in a headcase like Cromartie so losing Taylor could hurt.
