As the 2012 NFL playoffs get underway and four teams advance on to the divisional round, the savvy fantasy owner have already turned their attention to the 2013 season. Taking careful notice of players that may be able to help take their fantasy teams to the championship and finding excellent sleeper candidates is a year-round task.

They will often turn late-season opportunities for playing time into a chance to move up the depth chart for the following season or at least the chance to garner more snaps. The Individual Defensive Player (IDP) side of fantasy football tends fluctuate more from year to year than the offensive oriented formats, and deducing who is likely to sneak up draft boards before next August can never be started too early.

As we sit back and enjoy some excellent NFL playoff action, let's also look ahead at some names that could be sneaky good fantasy sleepers on the IDP side of things. As it is very early in the ‘offseason,' we'll sprinkle in a few names at each defensive alignment and examine their fantasy appeal for the 2013 season.

Don Carey, FS, Detroit: The Lions brought Carey on board in early November to help bolster a secondary beset by injuries and he produced some very nice totals down the stretch. He finished the season with 39 total tackles and a pair of interceptions while appearing in nine games. He was solid in run support and surprisingly effective in coverage with five passes defensed and allowed the Lions to release veteran safety Erik Coleman during the season.

Carey recently signed a one-year, $630,000 contract extension and is thought to be slotted into a reserve and special teams role for 2013. Louis Delmas has trouble staying healthy and is a free agent who may not be brought back, and the rest of the Detroit safeties are a motley group in disarray. Keep Carey in mind late in fantasy drafts as a stash with nice upside.

Nigel Bradham, SLB, Buffalo: Bradham stepped in Week 6 to replace Arthur Moats at the SLB position for Buffalo and looks to have cemented a starting gig heading into 2013. His Week 17 total of 11 combined stops helped him reach 57 for the season along with a pass defended. The entire Bills defense played much better as the season progressed and Bradham led the way. He also produced his numbers in limited playing time as the rookie out of Florida State averaged only 30 snaps a game, leaving the field when the Bills employed their nickel package.

He was a solid compliment to veteran WLB Nick...

Lions signed S Don Carey to a one-year, $630,000 contract extension.

Carey was scheduled to become a restricted free agent this offseason. He was signed on the first day of November with the Detroit secondary experiencing a slew of injuries. Carey, 26 in February, then started six games down the stretch and recorded two interceptions with five pass break-ups. He'll be a reserve and special teams player in 2013.

Lions signed DB Don Carey.

Carey was with the Lions in camp before getting released with an injury settlement. He's on as secondary depth with Louis Delmas (knee) banged up again and Bill Bentley (shoulder) out for the year.

Lions released DB Don Carey with an injury settlement.

Carey was on injured reserve after being waived/injured last Monday. A special teamer and reserve safety for the Lions last season, Carey is just two years removed from starting 10 games for the Jaguars. He could draw interest as a mid-season special teams fill-in.

Lions waived/injured DB Don Carey and TE Nathan Overbay.

A special teamer and reserve defensive back, Carey appeared in five games last season, making 11 tackles. He appeared in 15 games for the Jaguars in 2010, making 10 starts. Getting cut at this stage of camp bodes poorly for Carey's NFL future, but his experience should keep him on the radar. A third-year pro, Overbay has yet to appear in an NFL game.

Lions DB Don Carey sustained a concussion in Week 15.

Carey took a blind-side hit to the head on kickoff coverage last week. Unlike FS Chris Harris, the special teamer has yet to be cleared for a return to practice.

Lions signed S Don Carey, formerly of the Jaguars.

Carey was cut by the Jags before the season after totaling 36 tackles in 15 games last year. He'll add depth in Detroit with backup safety Erik Coleman out for the season.
