Not saying he isn't good - but I feel like so many are implying he's going to get a DC job...I think the defense is struggling big time...it has mediocre ends (Booker I like and is an ascending player..looks like a roational pass rusher at a minimum). But the interior of the D is very weak - Poles has failed miserably here (Jarrett, Dexter, Pickens, Shemar (injury), and the Colts guy have all been major investments whether draft picks or free agent spend - yet the production and interior penetration is weak. Running defense is bad, gap control is bad, etc. Dexter has flashed from time to time - but he looks more like a rotational piece than anything else.
But when your interior is weak and your ends are mediocre - the combo is even worse...combine that with a poor secondary sans Byard (I have been really bummed out on Brisker as he just doesn't look like the player he was before his concussion issues). Not saying he's bad - but he's not flashing a lot - just a solid safety. The DBs are horrendous - whether Gordon/Jaylon/Smith healthy would have changed that is a moot point.
Our LB play has been sub-par too. Edmunds was good to above average pre-injury...since than it hasn't been the same. Hopefully its more of he just isn't 100% (but trending in the right direction)...but that is just a soft D. Good thing is - some of those areas could improve with health / offseason...others could be filled / improved with solid draft picks (you can find good LB's in 2nd/3rd/4th rounds).
