Isaiah Crowell, RB, Alabama State
Perhaps the draft's most talented running back, Crowell went undrafted because of major off-field issues. The 5'11", 225-pounder has superb vision to go along with good speed, quickness and power. He isn't a perfect player, but he is at least a second-round talent on the field. This signing has huge potential.
Willie Snead, WR, Ball State
Weighing in at 5'11", 195 pounds, Snead is undersized but was extremely productive in college. In 2013, Snead caught 106 receptions for 1,516 yards and 15 touchdowns. It is difficult to imagine a player with Snead's combination of size and speed becoming too much of a player, however.
Anthony Dima, OL, Massachusetts
Dima is a big-framed offensive tackle who could kick inside to offensive guard. The 6'6", 290-pounder isn't a great athlete and would be better off at guard, where he wouldn't have to spend as much time playing in space.
Ray Agnew, FB, Southern Illinois
The son of the defensive tackle of the same name, Agnew is a stout fullback, measuring in at 5'10", 247 pounds. He is also a decent athlete, though, and could have the skill set to develop into a contributor.
Chandler Jones, WR, San Jose State
Jones' 2013 season was an extremely productive one, as he caught 79 passes for 1,356 yards and 15 touchdowns. The 5'9", 183-pounder is probably limited to playing out of the slot, but he is fast and quick with soft hands. Jones has a chance at competing for a roster spot with Cleveland.
Connor Shaw, QB, South Carolina
A broke man's Johnny Manziel, Shaw is an athletic passer, standing at just 6'0", 206 pounds. If he develops, Shaw could serve as an ideal backup for Manziel, as Cleveland would be able to run the same offense should Manziel go down with an injury.
Calvin Barnett, DT, Oklahoma State
A defensive tackle with the ability to penetrate, Barnett picked up 6.5 tackles for loss and three sacks in 2013. The 6'2", 317-pounder's size suggests he could play nose tackle, but his style of play is better suited for defensive end in Cleveland's 3-4 defense, where the team already has plenty of depth.
Carlo Calabrese, LB, Notre Dame
Though he has decent size at 6'1", 236 pounds, Calabrese isn't much of an athlete. The Notre Dame product did have 91 tackles in 2013, though, and it is possible that he could make up for his athleticism with superior intelligence and work ethic.
Blake Jackson, TE, Oklahoma State
The undersized Jackson isn't a fit as an in-line tight end. The 6'4", 230-pounder is athletic enough to move around the field, but he may not be dynamic enough to make up for his lack of size. Because of an injury, Jackson played in just four games during 2013. In 2012, Jackson caught 29 passes for 598 yards.
Jacques Washington, S, Iowa State
At 6'0", 207 pounds, Washington has terrific size at safety. He isn't a strong athlete, though, and will have to overcome a lack of range. Washington recorded an impressive 119 tackles in 2013.
Alex Bazzie, LB, Marshall
Over the past two years, Bazzie had a combined 146 tackles. The 6'1", 244-pounder has terrific size at inside linebacker in Cleveland's 3-4 defense but may be too slow for the NFL. Mike Pettine demands his linebackers be able to cover, and Bazzie may not have enough range.
Christo Lisika, LB, Southern Nazarene University
The 6'1", 235-pound Lisika is a solid athlete who demonstrated huge playmaking ability in college. His 18 tackles for loss in 2013 is a truly impressive number, though it obviously happened at a small school. Regardless, production should be taken seriously, and Lisika will have a chance to prove he can play against stronger competition.
Robert Nelson, CB, Arizona State
A great athlete, Nelson weighs in at just 5'10", 175 pounds. The Arizona State product was a star cornerback in college, but he projects best as a nickelback due to his size and quickness. In 2013, Nelson picked up 44 tackles and six interceptions, demonstrating some playmaking ability.
Nickoe Whitley, FS, Mississippi State
With 15 career interceptions, Whitley is clearly a playmaker. The 6'0", 205-pounder has good size but lacks great athleticism, and his poor tackling limits him to playing free safety. In order to last in the NFL, Whitley's intelligence and instincts will have to be excellent.
Jason Hendricks, SS, Pittsburgh
In 2013, Hendricks picked up 85 tackles, showing a nose for the ball. However, the run-defending safety weighs in at just 5'10", 182 pounds and lacks the size to play his type of game in the NFL. Hendricks would have to be special to make it, given his lack of size and coverage ability.
Greg Blair, LB, Cincinnati
Blair racked up 106 tackles in 2013, including seven for a loss. The 6'1", 244-pounder has excellent size, though he isn't anything exceptional athletically. It is possible, though, that Blair can overcome his lack of ideal speed and compete for an inside linebacker spot in Cleveland's 3-4 scheme.
Corey Robinson, QB, Troy
A four-year starter, Robinson was productive during his college career. The 6'0" quarterback isn't nearly as athletic as most the passers on Cleveland's roster, though he is undersized. Robinson threw for over 3,000 yards in his each of his seasons at Troy.
Gerald Ford, WR, Valdosta State
A 6'3", 223-pound wide receiver, Ford is a good athlete with tremendous size. Ford didn't play during the 2013 season, but in 2012, he caught 69 passes for 1,026 yards and 13 touchdowns. It is difficult to properly evaluate Ford given the level of competition he faced, but he is definitely talented.
Taylor Gabriel, WR, Abilene Christian
At just 5'8", 167 pounds, Gabriel is tiny, even by slot receiver standards. Gabriel is a tremendous athlete, though, with a 40" vertical. Though Gabriel was productive at Abilene Christian, gaining 1,060 yards in 2013, he will struggle to make an NFL roster, if only because of his size.
Antonio Gillespie, DT, Troy
With four sacks and 7.5 tackles for loss in 2013, Gillespie showed a definite ability to penetrate and make plays behind the line of scrimmage. The 6'1", 297-pounder lacks ideal length, but his style of play could work as a defensive end for the Browns.
Michael Philipp, OT, Oregon State
Throughout his career, Philipp started 48 games at left tackle. The 6'4", 316-pounder probably isn't long enough to stick on the outside, but he has excellent size for a guard. Philipp's athleticism is less than impressive, though, and he could struggle to make a roster.
Jonathan Krause, WR, Vanderbilt
Another potential slot receiver, Krause measures in at 5'11", 187 pounds. He was productive in 2013, catching 42 passes for 714 yards. This is despite playing opposite second-round pick Jordan Matthews, who drew many of Vanderbilt's passes as he dominated competition.
K'Waun Williams, CB, Pittsburgh
A 5'9", 183-pound cornerback, Williams is another player limited to covering the slot. His seven deflections and two interceptions in 2013 is nothing special, but Williams is a solid athlete. He will struggle to compete for a roster spot, given Cleveland's excellent cornerback depth.
Randall Harris, OT, Towson
Harris spent his college career blocking for Cleveland third-round pick Terrance West, and he joins his running back with the Browns. Harris lacks the size to play tackle in the NFL, measuring in at only 6'3", 296 pounds. His size is sufficient at guard, though, especially in the Browns scheme.
Darwin Cook, S, West Virginia
A good athlete, Cook had an extremely productive 2013 season, wracking up 74 tackles and four interceptions. The 5'11", 194-pounder has decent size for a free safety, though it wouldn't hurt if he added a few pounds.
