A fifth-round pick in the 2010 NFL Draft, Thomas never quite broke through in his four seasons with the San Diego Chargers picking up just 15 starts. He spent his last two seasons as a reserve lineman for the Pittsburgh Steelers.
Thomas clearly slides in nicely at the reserve DT spot as the Rams have some competition building for the spot abdicated by Nick Fairley who was signed a year ago before heading to the New Orleans Saints in free agency this offseason. Behind Aaron Donald and Michael Brockers, you've got a glut of newly-signed Dominique Easley, position tweener Ethan Westbrooks and lowkey option Louis Trinca-Pasat.
