Grab Vince Wilfork from FA - New England has a history of letting stars walk (Asante Samuel, Ty Law, Deoin Branch, etc.)
Grab Kirk Morrison from FA - No way he is staying in Oakland
ABSOLUTELY grab Vincent Jackson if he hits FA (which is highly unlikely)
Grab Shawne Merriman from FA - Chargers have already embraced for his departure by picking OLB Larry English in first round last year
Grab Marcus Howard from FA - Same with Morrison; why would anyone want to be in Oakland?
If we can make those offseason moves (all or some), we deal with our problems at NT/DT, ILB, OLB. Then we can focus on WR (Dez Bryant, Arrelious Benn, Golden Tate), RB (don't waste high pick on C.J. Spiller but instead pick Noel Devine in later rounds to use his speed to complement Brown's power), TE (Jermaine Gresham), DB (Earl Thomas), or to upgrade even more at LB (JErry Hughes, Rolando McClain).
