Bam Knight primarily served as a kick returner before being thrown into the starting lineup. He started eight games for the Cardinals as an emergency option/backup. He averaged 3.3 yards per carry on 82 carries. Knight had some "ok" moments and runs during last season. He caught the ball as a checkdown option in the shallow areas of the field. Best suited as an RB3/4, but within the right situation, can get you out of a pinch.

Michael Carter offers solid depth and backup running back. Last season, he started five games for the Arizona Cardinals due to numerous injuries in their backfield. Carter rushed for 333 yards and 267 receiving yards, displaying his dual-threat abilities. He brings confidence to the coaching staff in the depth behind the starter and primary backup.

Trey Benson has the frame, athleticism, and raw physical ability to make an impact as an NFL running back. Unfortunately, he's had to sit behind a good veteran back in James Conner as a rookie, and last season he was hampered by injuries. As a result, his development has stalled since he was drafted. He doesn't run with the consistent confidence or decisiveness needed to allow his raw athleticism to shine in the open field. His running style wasted time last year, with choppy, indecisive footwork when approaching a lane. The RB1 role will belong to Jeremiyah Love in Arizona for the foreseeable future; Benson has development to do.

Emari Demercado is a rotational backup running back with open-field speed. He's never surpassed 45 carries or 400 rush yards in a season. He's showcased the ability to generate explosive plays with the football after being forced into action for the Cardinals because of injuries. Demercado doesn't need a lot of carries to make an impact with his speed. He's limited to a backup role and potential kick returner.

Jeremy McNichols is a dual-purpose running back who excels in his role off the bench. McNichols is a trusted 3rd down RB because of his pass protection and pass-catching ability. He will help change the pace and give the defense a different running style. He does run hard and behind his pads. The 30-year-old back's prime is behind him, but he can sub in and make a few plays a game.

Jaylen Wright is an explosive athlete with homerun-hitting speed for chunk/explosive plays. He is stuck behind another dynamic and electric athlete, DeVon Achane, but when given opportunities, he has shown he can be a positive playmaker. Wright has flashes of good patience, footwork, and vision to find creases based on the defense's gap assignment and execution. He is not a productive or often utilized pass catcher out of the backfield. An expanded share of snaps and more touches can positively impact the Dolphins' offense. Until then, Wright is a capable backup running back.

Sean Tucker has served as the RB3 on the Buccaneers' offense behind Bucky Irving and Rachaad White. Tucker is an explosive runner with great open-field speed and acceleration. He follows blocks on gap concepts well. Tucker is a volume back who is better with more bites at the apple. He has shown flashes of starting-caliber play when given the touches. Tucker serves as a kick returner in Tampa Bay as another way to get the football in his hands. Overall, he's an athletic playmaker but has yet to carve out a prominent role in the offense.

Emanuel Wilson is an adequate backup and rotational running back. At his best, he's working off zone concepts where his vision and footwork allow him to get downhill quickly. He is a one-cut runner who excels after first contact. Wilson is not an overly elusive or explosive runner. He is a backup who can step in as a spot starter once in a while.

Kareem Hunt is a rugged and physical downhill runner. Whether gap or zone schemes, he is effective, churning out tough, hard-earned yards. In short-yard situations, Hunt is a go-to option to run with power and a forward/falling lean. Last season in Kansas City, he was a functional checkdown option and a great chip blocker for their tackles in pass pro. Hunt is far from his prime athletically. He has averaged under four yards per carry in consecutive years. While a solid contributor, he's a replaceable talent at this stage of his career.
