The Cardinals signed four undrafted free agents on Thursday, filling out the remaining spots on their 90-man roster.
Arizona cornerback Lorenzo Burns, North Carolina State tight end Cary Angeline, Oklahoma State defensive lineman Cam Murray and Cincinnati tight end Bruno Labelle make up the group.
The undrafted free agent class is usually much bigger, but the talent pool was small because the NCAA gave seniors another year of college eligibility due to COVID-19, so the Cardinals were more selective.
Burns, 5-foot-10 and 183 pounds, was the Wildcats' defensive MVP in 2019 and was named honorable mention All-Pac-12 in 2020. He tied for the Pac-12 lead with five interceptions in 2017 and amassed nine in his career. He is another potential option for cornerback depth, after the Cardinals selected Marco Wilson (fourth round) and Tay Gowan (sixth round) in the draft.
Angeline, who is 6-foot-6 and 250 pounds, had 27 catches for 412 yards and six touchdowns last season with the Wolfpack, earning honorable mention All-ACC accolades. Labelle only had 20 catches in his four-year career at Cincinnati but put up some impressive testing numbers at Pro Day, earning him a shot. The Cardinals are thin at tight end, so a good offseason performance by Angeline or Labelle could merit a chance to stick.
Murray had 22 tackles, three sacks and six tackles for loss for Oklahoma State last season. He will try to make an imprint on the interior of the defensive line.
