Following a 10-6 loss at home to the Jacksonville Jaguars, a game in which they failed to score a touchdown against the NFL's worst defense, it's impossible to feel good about the current state of the Tennessee Titans and increasingly difficult to feel good about the future. ... Coach Brian Callahan has not had the job for a full season but already he is on the hot seat. Does the fact that this franchise is building a new stadium and trying to sell pricey tickets for that venue help or hurt Callahan's chances to keep the job beyond this season? If he does survive, it is easy to think that Callahan should give up some of the responsibilities he took on in his first opportunity to lead an organization. ... Quarterback Will Levis continues to show improvement in some areas -- if you look for them. Overall, though, he is not doing nearly enough to make the offense consistently productive or to inspire confidence in that unit, let alone throughout the entire roster. ... The defense continues to look good statistically but -- surprisingly -- fails to deliver in key moments, as was the case Sunday against Jacksonville. ... This week, the Titans will face Callahan's former organization, the Cincinnati Bengals, which boasts exactly the kind of offense Tennessee thought it would get. Going head-to-head, however, it will be difficult for the Titans to keep pace.
