dude i dont know what you've been watching with CJ - he's an absolute beast in the middle of our defence who's much much more than a "run stuffer" - he was snubbed at 98 and the bottom half of that list is always weirdly because of the way the list is ordered (you have to be picked as a top 20 player by enough other players that you get in there) - but the accolades im talking about are 3x pro bowl, 3x 2nd team all-pro for example...
and i dont know that you are looking at our depth chart: if we purge all the old players our defence still next year consists of young exciting pieces...
willie henry, brandon williams, michael pierce, CJ mosley, matt judon, (wormley, bowser and timmy), marlon humphrey, tavon young, maurice canady, jaylen hill, chuck clark, tony jefferson
that doesnt even include rookies like elliott, averett, kenny young, sieler
even if we were to assume that wormley bowser and timmy all dont pan out and that we dont bring in any free agents or future draft picks - the defence still is really only short at free safety and edge... so yes the defence is absolutely stacked both now and moving forwards and that's even assuming all the 2017 day 2 picks dont pan out - which seems unlikely that none of them would work out...
now if they do continue to develop well then edge isnt an issue and our DL remains a solid unit and FS becomes the only real need on defence with depth at every other position and level of the defence
so respectfully i have no idea what you're looking at
