The DL has been bad. The players that returned from last year, Hughes, Oliver, Murphy, Phillips have all regressed and Star opted out. Picking up players from the used Panthers pile haven't matched J.Phillips or Lawson.
LB - Edmunds has regressed, Milano has been either hurt and out or hurt and playing anyway. Klein has not replaced Lorax.
CB - White isn't playing like he is capable of, Taron Johnson has regressed, Norman is sometimes good but often not so much.
S - Neither Poyer or Hyde are playing as well as they have in the past.
This defense has a lot of talent, why are so many of these talented players regressing this year. Something changed and it needs to go back to what it was.
