· Cornell Green has the early inside track on the right tackle job left vacant by Langston Walker's departure. Walker had a problem against speed rushers and he doesn't have a quick first step, which frequently put him at a disadvantage. Green has a similar body type to Walker but seems to be a little more fluid with his feet and moved around fairly well.
· Looks like Chris Carr's days as a punt returner might be over. While Carr worked out with the defensive backs, rookie wide receiver Johnnie Lee Higgins handled the return chores. Carr will likely retain his kickoff return duties.
· Veteran safety Donovin Darius looks like he'll make an immediate impact. Darius, who signed with Oakland after spending his first nine NFL seasons in Jacksonville, made two strong plays in practice, stripping tight end Fred Wakefield of the ball on one after Wakefield had made a short reception. Darius took turns subbing for Stuart Schweigert and Michael Huff while the Raiders try to figure out which combination of the two they'll use when the regular season begins.
Given the addition of Darius, it won't come as a surprise if defensive coordinator Rob Ryan decides to go with the 4-2-5 formation the team relied so heavily on two years ago. In that situation, the Raiders could use either Darius or Huff as a pseudo-linebacker, lining them up down in the box near the tight end.
