Another summer on the bubble for Saints safety Pierre Warren?

The New Orleans Saints' safety position, which was depleted by injuries last year, is suddenly overcrowded now that everyone is healthy.

The safeties are up next in my position-by-position breakdown of the Saints' roster battles leading up to the start of training camp. Players report to The Greenbrier resort in West Virginia on July 29, with the first practice July 30.

Position: Safety

53-man roster projection: Jairus Byrd, Kenny Vaccaro, Rafael Bush, Vinnie Sunseri, Pierre Warren

Missing the cut: Jamarca Sanford, Kenny Phillips

Analysis: Warren will be fascinating to watch this summer. He was a revelation in training camp last year as an undrafted rookie out of Jacksonville State but didn’t even make the practice squad because of the Saints’ depth at the position.

But then the Saints needed Warren back because of a rash of injuries, so they signed him off the Minnesota Vikings' practice squad in November and launched him right into the starting lineup at free safety. The 6-foot-2, 200-pounder held up well under the circumstances, even having a two-interception game in a Week 15 win at Chicago.

Now Warren is back on the bubble since the top four guys on this list seem relatively safe. But if he continues to flash his potential. If he can help on special teams, the Saints probably won’t let Warren get away again.

That doesn’t leave any room for veterans Sanford and Phillips, but I wouldn’t rule out either one of them to make the roster, especially if another injury creeps up. The 29-year-old Sanford finished last season as the Saints' starting strong safety, and the team liked what it saw enough to re-sign him.

Meanwhile, Phillips hasn't played in the NFL since 2012 because of knee and quadriceps injuries. But he's a former first-round pick and Super Bowl winner with the New York Giants, so the 28-year-old's comeback attempt will be interesting to watch.
