Four former Trojans have signed NFL free agent contracts after going undrafted in the 2014 NFL Draft — George Uko to the New Orleans Saints, Xavier Grimble to the New York Giants, Silas Redd to the Washington Redskins and Kevin Graf to the Philadelphia Eagles.

Uko was projected to be drafted between the fifth and sixth rounds, but he fell out of the draft completely.

Grimble and Graf were given seventh round projections, but their ending up in the free agent pool wasn’t much of a surprise. The same goes for Redd, whose lack of explosiveness was always a hurdle on his path to the draft.

At USC, Uko started 29 games at defensive end, logging 85 career takles, 11.5 sacks, a blocked FG and PAT, and a fumble recovery for a touchdown.

In 2013, Uko earned an All-Pac-12 honorable mention before making the now questionable decision to leave school early.

Grimble’s decision to leave early has also been questioned, as his three seasons as a Trojan were characterized by potential and injury. In 22 career starts, Grimble caught 69 passes with 11 touchdowns. He was named a 2013 All-Pac-12 honorable mention.

Graf started 38 games for the Trojans at right tackle. During his time at USC he was named a 2013 All-Pac-12 honorable mention and a CollegeFootballNews.com Sophomore All-American honorable mention in 2012.

Redd transferred to USC in 2012 following the NCAA sanctions against Penn State. In two seasons with the Trojans he rushed for 1,281 yards and ten touchdowns. He was a 2012 All-Pac-12 honorable mention in his first season before a string of injuries limited his final year.

Uko, Graf, and Redd join Dion Bailey, who signed with the Seattle Seahawks, and Demetrius Wright, who signed with the Miami Dolphins, as undrafted free agents in the NFL. Marqise Lee and Marcus Martin were both drafted — Lee to the Jacksonville Jaguars in the second round and Martin to the San Francisco 49ers in the third round.
