It's not exactly Robby Anderson but the Jets have reportedly brought back another member of last year's team.
Source: The #Jets re-signed safety Bennett Jackson, who spent time on the team’s 53-man roster & practice squad in 2019. Good special teamer with versatility in the secondary— Connor Hughes (@ConnorJHughes) March 24, 2020
Jackson, who will be 29 in September, didn't make his NFL debut until this season. He saw action in four games with the Ravens before the Jets were able to sign him for the second time in under a year. Jackson suited up twice for the Jets but only saw action on special teams. He had one tackle.
In case you're wondering how the hell you're supposed to know who that is, here's a link to his scouting report.
