Alex Collins

Cast off the Seahawks' roster at the end of the preseason last year, Collins wound up at the bottom of a Ravens depth chart that seemed nearly as crowded, but by Week 3 he seized the starting role and never looked back. While he lacks the straight-line speed expected of top-shelf feature backs, Collins proved to be one of the most elusive runners in the league, showing outstanding footwork and vision to find a crease and hit it with authority. The 23-year-old's ability to make defenders miss even in tight quarters allowed him to overcome the mediocrity of Baltimore's offensive line. Collins has the size and frame to handle plenty of snaps, but his skills as a receiver are still a work in progress, with limited cause for optimism. While Javorius Allen and Kenneth Dixon are around to pick up any passing-game slack, there's no reason to think Collins will fade away as suddenly as he arrived. The Ravens' O-line should improve with G Marshal Yanda returning from an ankle injury, and the team likely will run some zone-read plays if rookie QB Lamar Jackson gets on the field.

Collins got some valuable experience in his rookie season due to injuries to Thomas Rawls and C.J. Prosise. In 11 games, Collins recorded 31 carries for 125 yards, a touchdown and two fumbles (one lost) to go along with 11 receptions for 84 yards. However, with both Rawls and Prosise returning to health and the Seahawks adding Eddie Lacy to the backfield mix in free agency, Collins needed a strong training camp to earn a roster spot in 2017 and was unable to deliver. After going unclaimed off waivers, Collins signed with the Ravens' practice squad in September and will have to bide his time until injuries to the Baltimore backfield -- or any team for that matter -- create an opening for him.

A fifth-round draft pick out of Arkansas, Collins isn't physically imposing at 5-foot-11, 217 pounds and clocked just 4.59 seconds in the 40-yard dash at the Combine. However, he'll merely serve as depth to a Seattle backfield that is populated by Thomas Rawls (ankle), Christine Michael, and C.J. Prosise.
