44.) Colin Cole, DT - The seven-year veteran will be debuting with the third team of his career, and he will be trying to earn a spot as a backup to Star Lotulelei. Standing in his way will be Sione Fua, who will not make the challenge easy. Fortunately for Cole, he seemed to thrive over the past two seasons—although he last played in 2010—by appearing in 27 games and starting in all but one of them. He gives the Carolina defensive line some depth in an offseason that saw a tremendous amount of tinkering with the interior of the unit.
43.) Colin Jones, S - Jones played second-fiddle to Haruki Nakamura in 2012, and while he played in 15 games, he didn't start in any of them. That fact alone should be very telling about how weak the Carolina secondary was last year. The good news is that he will be returning for his second year with the Panthers and is familiar with the scheme that defensive coordinator Sean McDermott likes to run. That will give him a slight edge over the new guys in camp.
42.) Jordan Senn, OLB - Senn has mostly made a name for himself on special teams, where he has provided a big enough impact to be named as a team captain by his fellow teammates. Barring a gross amount of injuries, he should remain a staple on the special teams unit. If anything, he will be a reliable leader for a group that hasn't had much to boast about in recent years.
41.) Ben Hartsock, TE - He is not much of a receiving threat, as his duties are often limited to blocking assignments. However, he is regarded as the backup to Greg Olsen. Still, in 30 career appearances with the Panthers, Hartsock has only caught two passes. His last and only touchdown reception was in 2009 as a member of the New York Jets. He is a 10-year veteran in the league, though, so don't expect much to change regarding his role on the team in 2013.
40.) Kenjon Barner, RB - The lesson learned with Joe Adams should keep expectations from being too lofty. The rookie Barner has a lot of potential, and while he could be a valuable asset for Carolina, he is still sitting behind two established running backs and a bruising fullback on the depth chart. If he is to get his start, it will be on special teams. The Panthers need someone who can be a burner in the return game, and having someone capable of giving the offense great field position would make Barner's sixth-round selection a bona fide steal.
39.) D.J. Moore, CB - After spending the first four years of his career in Chicago, Moore will look to challenge for a spot in the secondary. Considering that particular unit was vulnerable in 2012, the position battle should be up for grabs. Moore put up some decent stats during his time as a Bear, despite starting in only three out of 45 games.
38.) Thomas Austin, C - Austin may not see too much of the center position, but considering the durability issues along the line, it's not a foregone conclusion that things will remain the same this season. He played in just four games last season and started in one of them.
37.) Ted Ginn, Jr., WR - Ginn was a highly regarded draft prospect who never seemed to harness his full potential. While he is a wide receiver, the majority of his playing time will probably be on special teams, where he will return punts or kicks. The best-case scenario for his signing will be for him to not only excel in the return game but also to be an under-the-radar threat on offense.
36.) Mike Mitchell, S - Another former Oakland Raider will trade silver and black for black, blue and silver in 2013. Mitchell has played in many games, but he has yet to be an everyday starter after four years as a pro. He will enter camp looking to challenge for a starting spot at safety, and he could push veteran Charles Godfrey to up his game a bit.
35.) Joe Adams, WR - It's pretty bad when the majority of a team's receiving corps is in the lower half of the rankings. Adams is here not so much for his lack of contributions on offense but more for his lack of focus on punt returns. He was drafted last year with the hopes that he could turn around a stagnant special teams unit, but after displaying a penchant for fumbling the ball, he lost his job for awhile. If Adams can get a few more reps in the offense this season, he could climb a bit higher in the rankings.
