NFL draft analyst Mike Mayock listed Utah running back Devontae Booker and Southern Utah safety Miles Killebrew among the top five prospects at their respective positions in his initial rankings released Wednesday for this year's NFL draft.

Booker comes in at No. 3 on Mayock's list of the top running backs, behind Ohio State's Ezekiel Elliott and Alabama's Derrick Henry. Booker rushed for 1,261 yards and 11 touchdowns last year and accounted for 63 percent of Utah's carries before going down for the season with a torn meniscus and bone bruise in his left knee in November.

The junior-college transfer was also a receiving threat, with 318 receiving yards last season.

Killebrew came in at No. 4 on Mayock's list of the top safety prospects, behind West Virginia's Karl Joseph, Ohio State's Vonn Bell and Boise State's Darien Thompson. Killebrew wrapped up his five-year career at Southern Utah, including a redshirt season, by rolling up a team-best 132 tackles, 2.5 tackles for loss, seven pass deflections and seven pass breakups in helping the Thunderbirds win the 2015 Big Sky championship.

He also played in the Senior Bowl last month, starting for the North team and playing 53 snaps (37 defense, 16 special teams) and adding a pair of late tackles in the contest.
