Oakland has already traded its third-round pick in this year's draft to New England for the pick used to select offensive lineman Mario Henderson in 2007, and its fifth-round pick to Denver for defensive tackle Gerard Warren.
The Raiders could try to recoup some of those lost picks by trading either cornerback Fabian Washington or Stanford Routt.
With Hall slated to start opposite standout cornerback Nnamdi Asomugha in what should be one of the league's best cover duos, Oakland's top two picks from the 2005 draft will likely be relegated to the bench.
Routt, the second-round pick in '05, moved past first-rounder Washington as the starter last season. Routt is better suited to playing nickel back, possibly making Washington the more likely candidate to be traded.
The Raiders have been very active during the free-agency season after winning just four games last season and a league-low 19 the previous five years.
Oakland has signed defensive tackles Tommy Kelly and William Joseph, receivers Javon Walker and Drew Carter, safety Gibril Wilson, offensive linemen Kwame Harris and Cornell Green to deals that could be worth more than $160 million.
The Raiders also placed the exclusive franchise tag on Asomugha, guaranteeing him about $10 million next season, and re-signed running back Justin Fargas to a $12 million, three-year contract that guarantees him $6 million.
