The Giants have expressed interest in linebacker Deone Bucannon, according to Paul Schwartz of the New York Post (on Twitter). Bucannon played under Giants defensive coordinator James Bettcher in Arizona and offers familiarity with his system. 
Bucannon started his career as a hybrid linebacker/safety and offers strong coverage skills. Still, the Cardinals have not been able to get much from him in recent years and tried to move him at last year’s trade deadline. Bettcher may feel that he’s in position to get the most out of Bucannon and the Giants’ front office is at least open to the idea of signing him.
Last year, Bucannon totaled just 38 tackles and one sack across 13 games (six starts). But, in the past, he has shown flashes of brilliance. In 2015, his sophomore year as a pro, the Washington State product tallied 109 tackles, three sacks, and an interception.
