The Titans defense is strong up the spine. Jeffrey Simmons, Rashaan Evans and Kevin Byard give the Titans a stout constitution up the gut. Simmons can beat blocks, especially against zone blocking concepts. Evans is an old school linebacker, who plugs gaps and is a trustworthy tackler. Byard is a well rounded safety with a combination of range, instincts and tackling prowess. Other than that? Holes everywhere. Particularly on the perimeter.
The Titans defensive backs particularly struggle underneath. That appears to be influenced by the decision to have the Titans play soft off coverage. This leaves them incredibly vulnerable to quick hitting passes to the sideline.
