Armstrong, 28, originally signed on with the Rams as an undrafted free agent out of Miami back in 2013. He lasted just over a year with the Rams before he was waived and later claimed by the Raiders in 2014.
Armstrong would go on to have stints with the 49ers and Giants before signing on with the Browns last year. Cleveland brought him back on a one-year deal this offseason, only to release him as they trimmed down to the 53-man limit.
The Saints signed Armstrong to a contract a few months ago before releasing him in October.
In 2018, Armstrong appeared in six games for the Giants and nine games for the Browns, recording 23 total tackles and no sacks or interceptions.
Pullard, 27, was taken in the seventh round of the 2015 NFL draft by the Browns. He was, unfortunately, to make the 53-man roster coming out of the preseason, but the Browns later signed him to their practice squad at the start of the season.
Pullard had brief stints with the Jaguars and Chargers before the Eagles signed him to a contract in August. He was waived soon after.
In 2018, Pullard appeared in nine games for the Chargers and recorded 17 total tackles.
Wilson, 27, is a former fourth-round pick of the Chiefs back in 2015. He was waived at the start of the 2016 season but later added to the Chiefs’ practice squad before eventually being called up a month later.
The Chiefs declined to tender Wilson a restricted offer in 2018, making him an unrestricted free agent. He signed with the Rams on a one-year deal worth $750,000. Wilson signed with the Jaguars this past offseason only to be released coming out of the preseason.
From there, Wilson signed on with the Cardinals for a short stint a few months ago.
In 2018, Wilson appeared in all 16 games for the Rams and recorded 35 tackles, one forced fumble, one recovery and two pass defenses.
