The Tennessee Titans are one of the most slept on teams in the NFL, and that very rarely has any sort of advantage.
Sure, you may get lucky and be a “trap” team, but unless you are really bad (which the Titans haven’t been for a while now) the opposing players and coaches prepare for you equally as hard as they would any other team.
The only real benefit from being overlooked is that maybe you get less opposing fan turn out when the Titans take on a team on the road, but I still think that is negligible.
