Let me preface this by saying to be on the bubble the player had to be on the team for most of last season so no rookies or off season free agent pickups (Garrard, Messam).
Marlon Moore - Has shown very little in two seasons and doesn't do enough on special teams to earn a roster spot...he'll be fighting for his spot come training camp.
Roberto Wallace - He's done less than more on the field in two seasons. At some point potential has to show up on the field or you need to cut bait and go. He does bring some good special teams play however and that will help his cause.
Jeron Mastrud - Was used mainly as a blocker and really doesn't bring much to the table. Doesn't seem like a fit in the WCO.
John Jerry - I know everyone seems to hold out hope that this kid finally has the light come on but unless he trims down into the low 320's at least and gets a lot quicker I don't see him fitting in the ZBS. He's more of a fit in a power blocking scheme.
Mike Pouncey - I just want to see if anyone is reading what I'm writing or just skimming the names or going straight to posting without reading the preface. He's in no danger and I think he'll fit nicely.
Ray Feinga - I think Guard is a real problem on this team. We have a lot of power type guys who can't pull and Feinga is one of them. I really think Derek Dennis will displace one of the Guards on the roster and I have high hope for Josh Samuda as well.
Jason Trusnik - The signing of Gary Guyton put Trusnik squarely on the bubble. He doesn't seem like a fit in the 4-3 and didn't do much outside of getting penalized a lot on special teams.
Austin Spitler - Another guy who hasn't done much except special teams. I think the 4-3 will help him but if he doesn't show up in a defense that's more a fit for him then I think he's gone and Josh Kaddu will take his spot on special teams.
Koa Misi - I've heard the rave reviews of how he looks better in the middle of the defense. The same rave reviews have been said about other players here before they were kicked to the curb. Something is fishy when the team goes out of it's way to single out a player that hasn't met expectations.
Chris Clemons - This guy fell of the face of the earth last year, from starter to nothing. He's not a good tackler so he's not able to play both safety spots, his coverage skills are not very good, he doesn't have a knack for making plays. I think he's in trouble.
Nolan Carroll - He was just toast for most of last season. Vincent Agnew has made the first statement by making plays in the rookie camp recently, granted that was against 1st year players and rookies but he got noticed...for the right reasons. He was on the practice squad last year and I think he's going to make a strong push for the roster. Richard Marshall being signed also doesn't help Carroll's cause.
There's 10 players that I think are on the bubble come training camp.
