In case you have lost track, gone from the New England Patriots' Super Bowl-winning secondary are starting cornerbacks Darrelle Revis and Brandon Browner, and now Alfonzo Dennard and slot corner Kyle Arrington.

Arrington, a valuable piece in the New England secondary since 2009, has been informed of his release, according to ESPN, a somewhat surprising development in an offseason of change for the New England secondary.

Perhaps the Pats have plans to move Devin McCourty back to corner. Or maybe not. If they don't, here's what they're looking at right now:

MALCOLM BUTLER -- It seems the Super Bowl hero will open the season as a starter. Given the lack of depth and experience at the position, the Pats will need Butler to take a step forward in Year Two and become a consistent starter.

BRADLEY FLETCHER -- After a rocky 2014 season in Philadelphia, Fletcher signed with New England at a relatively cheap price. He has good size (6-foot, 196 pounds) and has made 53 career starts. Fletcher should be in contention for one of the two starting gigs.

LOGAN RYAN -- An outside cover guy, Ryan will likely battle Fletcher for the second starting job.

ROBERT MCCLAIN -- Following the release of Arrington, McClain figures as the slot corner. He has plenty of experience playing the position in Atlanta, where he latched on in 2012.

CHIMDI CHEKWA -- A free agent acquisition from Oakland, Chekwa has primarily been a special teamer throughout his four-year career.

DARRYL ROBERTS -- The seventh-round pick from Marshall is a freak athlete. Few players in this year's draft matched his numbers from Pro Day. He also adds value as a special teamer.

DAXTON SWANSON -- Swanson spent most of 2014 on the Patriots practice squad. He was an undrafted free agent in 2013.

JUSTIN GREEN -- After spending time on the Patriots practice squad in 2013 and 2014, perhaps this is the year Green, a muscular 5-foot-11 corner, cracks the active roster.

JIMMY JEAN -- An intriguing post-draft add for the Pats. Jean, out of UAB, is a long and lean 6-foot-3, 180 pounds. He'll need to get stronger, but he has excellent length for the position.

ERIC PATTERSON -- The former Ball State corner signed a three-year contract with the Pats after going undrafted a few weeks ago.
