Zac Taylor has been on the job in Cincinnati for nearly 1 1/2 years. So far the Bengals have three victories to show for it. They also are 3-8 ATS the past 11 times as home 'dogs.
Taylor has a nice building block in rookie franchise QB Joe Burrow. But right now that's about all the Bengals have. And it's not nearly enough for them to hang with the Titans. 
Tennessee is averaging nearly 35 points during its last five games. Derrick Henry led the NFL in rushing last year and he ranks first this season by a wide margin. Ryan Tannehill has become a  top-10 QB and has a healthy set of receivers headed by A.J. Brown. 
The Titans are going to breeze past a Bengals defense that has below par linebackers and multiple injuries both in the defensive front and secondary. Veteran defensive end Geno Atkins hasn't been quiet in his criticism of the Bengals coaching. Cincinnati surrendered 20 fourth-quarter points to the Browns this past Sunday despite Cleveland being minus Nick Chubb and Odell Beckham Jr. 
The Bengals finished their game against Cleveland minus three starting offensive linemen. They also aren't likely to have RB Joe Mixon back either. 
The Titans are one of the most opportunistic teams in the NFL with a plus nine turnover margin.
