NEEDS: Coach Jon Gruden takes over team coming off disappointing season with many holes. There could be even more voids if Raiders choose to release several high-priced veterans to create even more cap room. Biggest holes right now are on defense; Raiders must upgrade at linebacker and in secondary, as well as find pass rush help for Khalil Mack. Oakland also would like to add at least one more receiver, along with possible upgrade at tackle. Another question is at running back; keep Marshawn Lynch and his $6 million salary or find starter in free agency or draft?
AVAILABLE SALARY CAP SPACE (approximately): $20 million.
