They’ve already added free agents with ties to Matt Patricia and Darrell Bevell. Next up could be a defensive back who used to play for Paul Pasqualoni.

The Detroit Lions are hosting safety Andrew Adams on a free-agent visit today.

Adams was non-tendered as a restricted free agent by the Tampa Bay Buccaneers on Wednesday. He spent his first two NFL seasons with the New York Giants, playing on the same defense as current Lions Damon Harrison, Romeo Okwara and Devon Kennard, and he starred in college at UConn, where Pasqualoni was head coach in 2011-13.

Adams had four interceptions in 13 games for the Bucs last year and has been a core special-teams player throughout his NFL career.

As an undrafted rookie, Adams started 13 games and had one interception for the Giants, and he made four starts each of the last two years.

The Lions agreed to terms with four players during the free-agent negotiating period: Defensive end Trey Flowers, cornerback Justin Coleman, tight end Jesse James and offensive guard Oday Aboushi.

Flowers and Coleman played for Patricia with the New England Patriots, and Aboushi played for Bevell with the Seattle Seahawks.

All four of those players are expected to compete for starting jobs this fall, and Adams could, too, if he stays in Detroit.

The Lions released ironman safety Glover Quin in a cost-cutting move last month and have yet to fill his spot in the secondary.

Tracy Walker, a third-round pick last April, is expected to take on a bigger role this fall, but Patricia said at the NFL combine last month that the starting job would be up for grabs heading into training camp.
