The Cardinals are among the teams interested in free agent cornerback Robert McClain, according to Aaron Wilson of the Houston Chronicle (on Twitter). Meanwhile, the incumbent Buccaneers are also hoping to re-sign him.

McClain, 30 in July, saw time both on the outside and in the slot for Tampa Bay in 2017. He amassed 46 tackles, five passes defensed, three interceptions, and one touchdown – a 47-yard pick six against Mike Glennon during his short stint as the Bears’ starting quarterback.
McClain’s best year came with the Falcons in 2012, though he also had a respectable year with Carolina in 2013 and looked solid last year with the Bucs. He could help to fortify the Cardinals depth chart as cornerbacks Tyvon Branch, Tramon Williams, and Justin Bethel remain in free agency limbo. Of course, the Cardinals are also without Tyrann Mathieu, who signed with the Texans after being released in a cap-driven move.
