Interior defensive line is a major weakness. They have a massive hole at DE with Peppers gone and the run defense will suffer as much as or more than the pass rush. If Brown doesn't develop, DE is a major weakness like DT. LB is solid although they could use a 3rd to go with Beason and Davis. Davis is coming off a torn ACL, so he will probably struggle for the first half of the year. Marshall did not get a first round tender and it makes me wonder if he will be back. If he leaves, DB is a weakness. WR other than Smith is a major weakness. They need a WR2 bad and probably a WR3 too. Moore played well, but he is still a question mark.
I see quite a few holes. A lot depends on how fast Davis recovers and the development of Brown at DE and Moore. I see a .500 team at best.
We dropped Kemo at DT who wasn't recovering well from achilles surgery and Lewis who was doing ok but not great and getting older. The DT's at the end of the year, weren't spectacular, but held their own against teams like Minnesota and the Giants (won't count New Orleans because they left a lot of starters out). Signing Ed Johnson to replace Lewis probably covers that spot and we may take a look at another DT in the draft. At DE, Brayton returns as a good run stopper and decent pass rusher (believe he had 5 sacks last year). Brown has another year to grow and get stronger and Charles Johnson is starting to show promise as another good but not great DE. Hilee Taylor taken a couple of years ago is a pass rushing specialist. Whether or not he takes the next step up is the question. I can see another DE drafted and possibly one picked up in FA. They won't be a great defensive line, but not the bottom either.
As to the LB's, Beason is the heart of the defense. Davis is coming off ACL surgery, but all reports are that he's coming along nicely and is looking good (already started running a couple weeks ago). SLB Na'il Diggs was released, but Dan Connor (3rd rd draft pick with 1st rd grading) should fill that slot. If he doesn't cut it, James Anderson is back who played the last couple of weeks and did relatively well.
The defensive backfield is doing ok as well. A lot of folks in Carolina wouldn't mind seeing someone pick up Marshall and taking the 2nd. Marshall is a decent player, but his position 2 years ago is that he wants to be the highest paid DB in the league and that hasn't appeared to have changed much. With Captain Munnerlyn, Sherrod Martin, and CJ Wilson, Carolina has a decent coverage should he leave. That leaves Chris Gamble on the other side with Chris Harris at SS and Charles Godfrey at FS.
Moore played well enough at the end of 07 and 09 to get his shot. I don't think he'll be handed the starting job, but I think he wins it easily unless he really bombs.
WR is definitely a question mark and needs to be answered. The interesting thing was to see Jarrett actually play well with someone other than Delhomme under center. Moore doesn't lock onto Smitty the way Jake did which bodes well for the team. He likes to go to the other WR's and TE's as well. Probably one of the first two picks in the draft goes to WR and possibly 2 out of the first 3.
Most of Carolina's moves this year appear to be a push to get younger and get those players playing time as well as reducing salary. This makes a lot of sense for 2011 should the cap be reduced. Remember, JR Richardson is on the owners finance committee, so he may be preparing the team for the future. Also, Carolina should be in for a much easier schedule this year as well. I believe they played a top 3 schedule last year with over half of the games against teams that made the playoffs.
