We all know the importance of having impact players, but a high pick doesent nessesaraly mean a player will become a stud at that position. The Raiders have many needs to fill and not a lot of free agent spending money. Some of the most successful teams(New England,Pittsberg,Giants) built there teams without the benifit of drafting in the early rounds.
Judging by last years draft, there's good value for teams willing to trade down( Baltimore traded their first-round selection (8th overall) to Jacksonville for Jacksonville's first-round selection, two third-round selections, and fourth-round selection (26th, 71st, 89th, and 125th).

Last years draft set the record for most trades in any draft.
This could be a better way to address the teams needs.
