With a relatively ugly cap situation, the Las Vegas Raiders are going to have to make a majority of their improvements through the 2021 NFL Draft this offseason. While the Raiders have needs on both sides of the ball, it is their defense in particular that needs the most work. Las Vegas allowed 29.9 points per game last season, the third-most in the entire league. They have hired Gus Bradley to replace Paul Guenther as defensive coordinator and he should help stabilize the unit. That being said, the Las Vegas Raiders still have major needs at all three levels of the defense and finding impact defensive talent will be the Raiders’ priority in this seven-round 2021 NFL mock draft.
