Childs Walker, reporter: The Ravens delivered a startlingly listless performance in the first half. They couldn't give Joe Flacco throwing time or stop a Tennessee offense that had struggled to move the ball all season. But quality won out over time. The Ravens' front seven gradually ratcheted up the pressure rookie quarterback Zach Mettenberger. And on offense, the Ravens neutralized Tennessee's rush, then wore down a poor run defense in the fourth quarter. With the Bengals and the Steelers both looking awful this week, the Ravens are right back in the AFC North mix, whether they played well or not.
