1. OLB Barwin, 2. OLB Quinn
Trade down to early second and pick up OLB Harold Landry. Then pick up OLB Marcell Frazier in the third. Plus, Ebukam showed promise when he went in for Barwin. Going with those three should bolster pass rush and save cap room at the same time.
3. NT Westbrooks
Move Brockers back to NT. Have Easley man one of the DE positions. Draft NT Tim Settle in the third for NT depth.
4. TE Higbee
Sign a vet TE. I would like to see Jimmy Graham in this offense. But there are other vets avail to upgrade this pos.
5. CB Webster, 6. CB Johnson
We still have NRC, Webster and Hill. Draft CB depth in the 4th. CB J.C. Jackson might fall to the 4th because of off field concerns. Plus, there are a ton of FA options for CB. Gaines who has familiarity with our D is also avail.
One thing you didn't mention is right side of OL. I mentioned RT before, but looking at PFF grades Havenstein graded ok. Brown on the other hand graded poorly. There are actually better options at G than at T this year so there a good opportunity to upgrade RG pos.
