Tennessee D/ST Playoff Quality

So just started looking into D/STs for Playoffs time. Saw Titans Def were FA in my league and their schedule is;

Jets 13
Jax 14
Giants 15
Washington 16.

and they’re rank 9 in scoring this year so far.
Am I missing something or are they worth rostering?

im def interested in this too. bills and titans available. currently have the ravens defense but our league still rocks the 14/15 and 16/17 for playoffs.

your not missing anything. I would roster If i was a lock and needed a D. Im a lock so I picked up the new england D and the ravens
