As part of this slow time on the NFL calendar, when we'll be taking a break to recharge for the 2014 season, we introduce the pre-produced "checking the locks" series in which we analyze the players on the Patriots' roster who are "locks" to stick. Today, it's safeties.
Analysis: With the Patriots releasing veteran starter Steve Gregory in late February, it opened up a top role on the depth chart next to McCourty, and 2013 third-round pick Harmon is the leading candidate to fill it. Harmon served as the No. 3 safety last year, making three starts and playing on 36.9 percent of the defensive snaps during the course of the season. Special teams figures to play a significant role in which players earn the backup spots, and third-year player Ebner was working as the personal protector on the punt team in spring practices, which is a key role. Depending on how many safeties the Patriots keep, 2012 second-round pick Wilson could be on the outside looking in after his defensive plays dipped from 42.5 percent as a rookie to 1.6 percent in 2013.
