Bradley Roby, Texans

Roby is another corner with ties to Cory Undlin and also a schematic familiarity with the Lions defense from playing in Houston, where Romeo Crennel (whose system Matt Patricia’s defense is based upon) was the defensive coordinator.

The 27-year-old Roby can play inside or outside, and he’s capable of playing off-man or pressing tight in coverage. Roby can make plays on the ball, with three pick-sixes in the last four years.

He will be playing for his third team in as many seasons, barring the Texans keeping him. At times it’s easy to see why the Broncos and Texans got frustrated with Roby too; he is vulnerable to double moves and is very weak — more missed tackles than stops in the last two years per PFF — in the tackling department. That also makes him more affordable for potential suitors like the Lions.
