If we add a premium edge rusher in the draft (Chaisson or Baun) or in FA (Griffen) I'd feel pretty comfortable with our DL, even if we didn't draft a DT.
Lawrence/Gregory/Crawford/Armstrong/new addition is fine at DE and McCoy/Poe/Woods/Crawford/Hill is fine at DT.
I'd still draft Kinlaw without a second thought or a guy like Gallimore in the 2nd, but I wouldn't feel like we'd be completely fucked if the board didn't fall that way.
I wouldn't put Gregory and Hill in the same category either. Gregory is a proven commodity if he can stay on the field, which seemingly isn't an issue with the change in weed policy, while Hill is a complete unknown who may very well be an unmitigated bust.
