Joe Webb, QB
This signing did indeed raise a few eyebrows, especially with Derek Anderson returning as Cam Newton's backup. However, Ron Rivera stated Webb would be a great player to look at while Newton is on the mend from his ankle surgery. It is possible the Panthers will carry three quarterbacks this season with the hope that Webb's similar skill set to Newton and growth allow him to assume the backup role in the future.
Derek Anderson, QB
Purely a case of keeping familiarity intact. Anderson and Newton have great chemistry together, and despite only appearing in limited action while in Carolina, Anderson has proven to be a reliable backup whenever called upon.
James Dockery, CB
Despite appearing in only 12 games as a member of the Carolina Panthers, Dockery is a decent backup when healthy. Not too much should be expected from him, as he will most likely serve as a depth player on the roster.
Richie Brockel, FB
With Mike Tolbert holding down the starting fullback duties, Brockel is nothing more than a backup who can be inserted at tight end if needed. Brockel may not see too much action, but when his number is called, it could be a trick play.
Garry Williams, OL
The Carolina offensive line is in dire need of help. Williams could be an option as a backup at tackle, but if the worst-case scenario presents itself, he could be called upon to start. For now, his impact level is solely depth at a depleted position.
Jason Williams, OLB
Known more for his special teams play than anything, Williams returns as a solid contributor on the unit and could fill in as a backup to give starter Thomas Davis or Chase Blackburn a rest.
Mike McNeill, TE
Having already been a part of the Indianapolis Colts and St. Louis Rams, McNeill is still trying to find his niche in the NFL. He hasn't been a solid contributor at the pro level, but his college numbers at Nebraska suggest he is very capable of being a pass-catching tight end. He will probably compete with Brandon Williams to back up Greg Olsen.
