2015 St. Louis Rams undrafted free agents

The St. Louis Rams signed 15 undrafted free agents after Saturday's NFL draft. Here's a closer look at each player:

Malcolm Brown, RB, Texas -- Rushed for 2,678 yards and 27 touchdowns in his career for the Longhorns. Enters a crowded backfield in which he'll likely compete with the likes of Trey Watts and Chase Reynolds for a spot, assuming he can contribute on special teams.

Imoan Claiborne, CB, Northwestern State (La) -- Played well enough in college to earn an invitation to the Senior Bowl after posting three interceptions and four fumble recoveries in 2014. Said he had a "large number" of teams calling for his services as the draft came to an end.

Isiah Ferguson, WR, Arkansas Pine-Bluff -- At 6-foot-5, 218 pounds, Ferguson is one of the most physically imposing of the team's lot of undrafted rookies but didn't have a ton of production last season as he finished with 29 catches for 343 yards and a touchdown.

Terrence Franks, RB, Texas State -- Franks had 712 yards rushing and 11 touchdowns last season and will face the same battle as Brown in his attempt to make the roster. He's related to professional basketball player Rashard Lewis and Tennessee Titans fullback Ahmard Hall.

Montell Garner, CB, South Alabama -- Finished with 54 tackles and two interceptions in 2014 after posting 60 and three as a junior. Comes from an athletic family in which his father, Milton, played defensive back for Kansas State and his mother, Kamita, ran track for the Wildcats.

Jacob Hagen, S, Liberty -- Earned a reputation as something of a ballhawk in 2014, finishing with eight interceptions, four forced fumbles and 108 tackles.

Jay Hughes, S, Mississippi State --A 2014 team captain, Hughes had 26 tackles, two pass breakups and two interceptions in 2014. That came after a 2013 season in which he missed the final 12 games because of an Achilles injury. His father, Tony, is the assistant head coach for the Bulldogs.

Zach Laskey, FB, Georgia Tech -- More than just a lead blocker, Laskey rushed for 2,033 yards in his career for the Yellow Jackets' triple-option-based offense. Is the only true fullback now on Rams' roster, though tight end Cory Harkey spends plenty of time at the position.

Matt Longacre, DE, Northwest Missouri State -- Holds school records for sacks (30.5) and tackles for loss (47) on his way to earning Mid-America defensive player of the year status in 2014 and All-American honors in his junior and senior seasons.

Cameron Lynch, LB, Syracuse --A team captain, Lynch finished with 97 tackles and seven sacks in 2014. There's room to fight for a roster spot at linebacker but special teams will play a key role in that.

Keshaun Malone, LB, Bacone -- For the second year in a row, the Rams added a defensive player from tiny Bacone after working with defensive tackle Deantre Harlan last year. Earned his conference's defensive player of the year award in 2014 when he had 135 tackles and five interceptions.

Bradley Marquez, WR, Texas Tech -- An accomplished baseball player, Marquez spent two years in the New York Mets minor league system. In 2014, he played in 12 games with 65 catches for 821 receiving yards and 10 touchdowns.

Tyler Slavin, WR, New Mexico Highlands -- Finished with 119 catches for 1,418 yards and 17 touchdowns in 2014. Started his career at Arizona before transferring.

Louis Trinca-Pasat, DT, Iowa -- From a Romanian family in which he's the only one of five kids born in the United States, Trinca-Pasat went to the Senior Bowl and Scouting Combine but went undrafted. He finished with 69 tackles and 6.5 sacks last season.

Darrell Williams, OT, South Florida -- Made 29 starts at left tackle in his final three seasons in college. A native of Jamaica, who came to the United States in ninth grade.
