There will definitely be pressure to add something offensive.
After dropping two DTs in the first two rounds, it will be a tougher argument to supplement the defense again this time.
The biggest need on the depth chart at this point is TE - where the team realistically has two guys (Greg Olsen, and blocker Ben Hartsock, depending on how you feel about sometimes-fullback Richie Brockel). A 2nd TE wouldn't hurt at all. But at 108, a lot of the steam seems to have come out of TE - notably losing Jordan Reed, the smallish Florida product.
What remains? the massive Nick Kasa, a 6'8, 270 lb Colorado guy who's mostly there for size; similarly, the shifty Joseph Fauria from UCLA has a lot of size. Those are my guys, but those aren't necessarily the highest rated guys, either. I don't think great value is there at 108.
The more pressing of the two needs, to me, is OL.
A tackle is almost always better value, and Oday Aboushi from Virginia fits that bill. He's a natural LT, and that might not be the immediate need, but it may allow the team to move some things around long term. David Quesenberry is an athletic guy as well - potentially more athletic. But he's also a guy who could play guard in the meantime, with a good nasty streak and a wide frame.
Barrett Jones isn't just a center. I keep hearing that. He's played LT in the SEC; he's played guard. I like him for verstatility, but he's also a somewhat natural right side player. At this spot, he'd probably find himself starting at RG again. Carolina doesn't really need a center, they need an upgrade on Geoff Hangartner.
The last spot I could see something? Safety. I could see them grabbing a competition player for Mike Mitchell, and the entire secondary is essentially on a one year deal for non-rookies. That includes the very cuttable FS Charles Godfrey. Corners are on one year deals, but at this point it's all competition to stay. S, they've only really brought in one new guy.
So, plenty of options at S right now. Probably through the 5th, too. Zeke Motta is a very interesting football player, who makes some sense to fall since he's not special athletically.
If you can get some of the over-aggression out of him on playaction, Duke Williams is athletically the real deal and has 4 years started at a rising program in Nevada. Phillip Thomas has FS style ballhawking skill as a SS.
