NY Giants
Bruce Johnson CB: It not that Johnson was a below-average player (to the contrary) but he is coming off a torn ACL and enters an even crowded cornerback position than the one he left during last preseason. Not only does he have to contend with second-year pro Prince Amukamara, but the team drafted Jayron Hosley, signed Antwaun Molden and Janzen Jackson and brought back Justin Tryon.

DT Corey Williams 6.1 million cap number may lead to his cut

Kansas City
Jake O’Connell TE
While versatility is a trait Scott Pioli cherishes, one has to wonder about this guy. With Tony Moeaki and Kevin Boss being their primary tight ends, and Steve Maneri's new role is as a No. 3 blocking tight end (at 290 lbs), who can also play offensive tackle, just where does O'Connell fit?
It's highly unlikely to be at fullback, when one considers that the Chiefs may go into this season without one. With either Shane Bannon or Taylor Gentry filling that role, his only chance of making the team is as insurance for the often injured Moeaki.
Jerrell Powe: Nose Tackle
Although it is unlikely Powe won't make this roster, one has to wonder about his lack of production last year.
In 2009, Powe played at 365 pounds at Mississippi and was so dominant, many scouts felt he could have been a first-round pick. He had one problem though, he lacked balance.
He dropped his weight down to 300 in 2010 but became such a non-factor that he lasted until round six of the 2011 draft.

RB Montario Hardesty
On paper, it seems like Hardesty has the most uphill of battles. Hardesty was brought on to be an every-down back, but now that Richardson's in sole possession of that role, Hardesty is a bit expendable. Add into the equation Hardesty's injury history, and it seems like the Browns would be smart to part ways with him.
FB Owen Marecic

Dolphins
Steve slaton RB

Philly
Darryl Tapp DL
Darryl Tapp is at risk of being one of these casualties and is strictly on the bubble because of his pay, not his play.
Tapp recorded 27 tackles and 2.5 sacks in 2011 as a situational pass-rusher, but is scheduled to earn $2.575 million during the upcoming season.

Ravens
Sergio Kindle DE/LB

saints
none

Falcons (safeties)
Tanard Jackson and Madieu Williams were brought in to help at free safety, however, and one of them—including incumbent DeJon Gomes—will be on the outside looking in.

Indy
Dwight Freeney DE 14 million cap number makes it seem like he could be cut, because no team will trade for him at that number

Tampa Bay
Kellen Winslow TE- could always use another dynamic stud TE. Winslow has never been deep into the playoffs and needs a career turn around and could come cheap if released.  With a 5 million cap number it is possible

san diego
shaun phillips OLB. 5.2 mil cap # and lower recent production could lead to his being cut
