Jarrett Lee (QB)
Former LSU quarterback Jarrett Lee may impress coaches at training camp, but a roster spot for him is doubtful when the season opens. Lee will be competing with Charlie Whitehurst, who has familiarity in the Chargers system.
Taylor Embree (WR)
A product of UCLA, wide receiver Taylor Embree finished his senior season with 20 catches—third most on the team. He also finished his career as the eighth-ranked player in UCLA history in receptions with 137. Embree's chances of making the team are slim, but he has the best chance of all the undrafted rookies at landing a roster spot.
Phillip Payne (WR)
Former UNLV receiver Phillip Payne became the school's all-time leader in receiving touchdowns last season when he hauled in his 26th touchdown catch against Colorado State. Like Embree, Payne will be fighting an uphill battle to make the team, but all the talent is there.
Michael Hayes (RB)
After finishing his career at Houston, running back Michael Hayes will attempt to crack San Diego's running back committee. The only problem is that Hayes will have too many competitors in his way to make the team.
DeAndre Presley (CB)
DeAndre Presley spent the majority of his college career playing quarterback for Appalachian State, but he's so athletic, that scouts projected him as a potential wide receiver or defensive back. On the Chargers' official roster, Presley is listed as a defensive back, but he was relegated to kick returns for the most part in mini camp and OTAs. Presley could compete for the return job, but he has veteran competition to worry about.
Jason Barnes (WR)
Jason Barnes posted average numbers during his career at South Carolina, and average won't be good enough to be out the other more qualified receivers in the mix to make the team.
Josh Linam (ILB)
Josh Linam started 11 games for UCF at middle linebacker, recording 66 tackles, two sacks and 10 tackles for a loss. With Donald Butler and Takeo Spikes manning the middle of San Diego's defense, Linam may have a shot at a reserve spot.
Logan Harrell (DT)
Starting all 13 games for Fresno State, defensive tackle Logan Harrell finished his senior season with 71 tackles, 17 tackles for loss and six sacks. If he really performs well in training camp, Harrell could join a rotation with Antonio Garay and Cam Thomas, but it's no guarantee.
Eddie Brown (DT)
Former Texas A&M nose tackle Eddie Brown finished his 2011 season with 29 tackles, four tackles for loss and three sacks. Unfortunately, it's going to take a lot more than that to guarantee a spot on San Diego's defensive line.
Sean Cattouse (S)
Sean Cattouse finished his college career with 75 tackles and four tackles for loss with the Golden Bears. A reserve spot could be a realistic goal considering how thin Chargers are at safety after their starters.
Mike Harris (OL)
Mike Harris is a huge offensive tackle at 6'5", 326 pounds out of UCLA. But, Harris will need more than just size to get his name on the roster.
Mohamed Marah (FB)
Mohamed Marah is an athletic fullback with experience at linebacker and defensive end. However, the San Jose State Spartan will have no chance at making the team with Le'Ron McClain and Jacob Hester handling the fullback duties. Marah would have to find a home at another position if he's interested in making the team.
Nick Guess (LS)
Tennessee alum Nick Guess will attempt to beat out three-year man Mike Windt for the job of long snapper.
Paul Cox (WR)
A product of Mississippi Valley State, wide receiver Paul Cox finished last season with 36 receptions for 619 yards and three touchdowns. Like many of the receivers, Cox will be fighting for limited space on the Chargers roster.
Greg Gatson (DB)
In his career at Arkansas, cornerback Greg Gatson appeared in 21 games, recording 25 tackles and just one interception. From his stats alone, Gatson is a long shot to make the team.
Michael Willie (WR)
In two seasons at Arizona State, wide receiver Michael Willie caught 72 balls for a total of 897 yards and two touchdowns. Limited in experience, Willie joins the rest of the receivers trying to get some attention for a roster spot.
