The Arizona Cardinals have made it a mission to improve their interior defensive line after injuries derailed the position last season as two starters missed most of the year. Justin Jones missed their final 14 games with a triceps injury, and Bilal Nichols missed their last 11 with a stinger. To address their needs, the Cardinals re-signed L.J. Collier and signed Dalvin Tomlinson.
