There were some compelling story lines that emerged this week. The Bengals took a not-so-surprising plunge back to earth after beating the Steelers and Ravens. The Giants were undressed. The “Sanchise” took it on the chin 5 times and the Jets found a new way to lose. The Vikings showed just how tough they’re going to be down the stretch. (It looks an awful lot like the Saints and Vikings are going to play for the NFC Championship.) The Eagles did the unthinkable. With all of these stories, perhaps nothing was more surprising that the rapid and complete demise of the once-proud Tennessee Titans.
