Raiders general manager Reggie McKenzie doesn't understand how the NFL awards compensatory draft picks, and he doesn't much care.

All McKenzie knows is he has three additional picks to go along with the two he inherited when the NFL draft begins April 26. The Raiders were given picks in the third (No. 95), fourth (No. 129) and fifth (No. 168) rounds.

Of the 32 compensatory picks awarded, the Raiders had the first, the third and the 10th.

"Whatever the formula is, I love it," McKenzie told reporters by conference call Monday. "I thought I would get a (third), a high one for Nnamdi (Asomugha), but this is better than expected."

Compensatory picks are awarded on the basis of losses and gains of free agents in the previous season. A year ago, Asomugha, tight end Zach Miller and guard Robert Gallery signed with other teams and started. Other free agents included linebacker Thomas Howard and quarterback Bruce Gradkowski.

The Raiders' biggest free-agent signing was tight end Kevin Boss, who has since been released and signed with Kansas City.

Before the compensatory picks were awarded, the Raiders only had picks in the fifth and sixth rounds, having traded draft choices in deals involving quarterback Carson Palmer and linebacker Aaron Curry. They also made draft-day trades last year to move up and select cornerback DeMarcus Van Dyke and tackle Joe Barksdale and spent their third-round pick in 2012 on quarterback Terrelle Pryor in the supplemental draft.

Compensatory picks come at the end of each round and cannot be traded, but McKenzie said he isn't ruling out dealing players for more draft picks.

"That could be possible," McKenzie said. "I never close the door on trades."

There can be value at No. 95. New Orleans found tight end Jimmy Graham out of Miami in that spot in 2010, and the New York Giants selected wide receiver Mario Manningham (now with the 49ers) at No. 95 out of Michigan in 2008.

McKenzie said he isn't expecting many moves before the draft, whether it be adding second-tier free agency or releasing players.

"I think the bulk of it has been done," McKenzie said. "At this point it's going to be production and talent. It's not going to be about money, money, money as far as the comings and goings of players -- the goings, mainly."

Cornerback Pat Lee, a former second-round pick of the Green Bay Packers, is still expected to be added to the roster, McKenzie said.
