The Oakland Raiders are the lone team in the AFC West to stick with the traditional 4-3 defensive scheme.
Denver and Kansas City are planning to transition to the 3-4 defense, and San Diego has long used the 3-4 scheme.
The Raiders do have a new defensive coordinator in former San Francisco and Seattle assistant coach John Marshall. Marshall has been quiet since he took over in Oakland but his history is to run a 4-3 defense.
The Raiders tried to use a 3-4 in 2004, Warren Sapp's first season in Oakland. However, it never worked and the Raiders scrapped it. Oakland's current personnel fits the 4-3 defense better, anyway, so expect the Raiders to skip the 3-4 party in the division.
Interestingly, though, it wouldn't be a surprise if the Raiders added a player that the 3-4 teams in the AFC West are studying in next weekend's draft: Boston College defensive tackle B.J. Raji. He also fits the 4-3 defense. While Raji may not be Oakland's top choice, he could end up being Oakland's selection at No. 7.
