Area of need: Linebacker
Current situation: Arizona is losing all three of its starters at linebacker, so that's the biggest area of need entering 2017. Injuries have been a major factor, but Arizona hasn't been good on defense by any stretch of the imagination recently, allowing 38.3 points per game in 2016.
The Wildcats can't expect a reincarnated version of Scooby Wright III to return to save them on that side of the ball, but they do need sturdy linebackers to emerge in place of Michael Barton, Paul Magloire and Tellas Jones.
