Detroit added several players to its secondary during the offseason, but returning CBs Chris Houston and Aaron Berry took the majority of first-team reps during OTAs alongside safeties Amari Spievey and Louis Delmas. Minicamp represents the final chance for newcomers like veteran CB Jacob Lacey, and rookies Chris Greenwood, Jonte Green, and Bill Bentley to make an impression before training camp. Unless one of the new arrivals excels during the three-day camp, expect Detroit’s returning back four to remain atop the depth chart.
