DT Neville Gallimore
Gallimore was written off as a post-June 1 cut last offseason and a 53-man roster cut, but he managed to make the roster and carve out a role on the defensive line. The Cowboys could always bring Gallimore back on a cheap one-year deal, but nobody would argue that he's disappointed as a former third-round pick.
OT Chuma Edoga
Edoga was signed for depth along the offensive line. He's filled in admirably at left tackle in the five games Tyron Smith has missed, but his dreadful performance against the Dolphins has fans ready to move on. The Cowboys have to find a better backup LT given how much time Smith has missed in his career.
CB Noah Igbinoghene
Igbinoghene has been invisible since the season-opener when he returned a blocked field goal for a touchdown against the Giants. Though heavily involved on special teams, he's played just 25 defensive snaps and has been a healthy scratch for 11 games.
LS Trent Sieg
The Cowboys signed Sieg to replace former long snapper Jake McQuaide signed with the Lions in free agency.
