Attachou and James I'm watching closely out of those guys in particular.
Some I'm interested in:
Kevin Pierre-Louis, LB (KC) Unlikely to start from the outset perhaps since he has to get up to speed, but he's getting a few first team reps and I don't think that the Chiefs would have traded away a good special teams player in DJ Alexander just to get back a guy who they intend to play on special teams. I think they will at least give him a look as the season goes on and the depth chart is pretty unsettled there. Maybe more interesting for dynasty as a Derrick Johnson replacement but worth watching in any case. If he got a chance, his athletic profile is very intriguing.
Ben Gedeon, LB (Min) - In competition for the WLB role with Lamur and has started mixing in with the first team apparently. Decent prospect, not flashy, but could be some value there in deeper leagues if he wins it.
Jayon Brown, LB (Tenn) - A bit quiet early in camp, but I've read some good things more recently so I'm keen to see if he makes more of an impression over the next few weeks. He's fast and good in coverage so you'd think he'll have a role, given that the Titans aren't strong at LB, but the concern is his ability against the run. It's a little discouraging that he didn't seem to separate himself from some other mediocre LBs early in camp, but he is a rookie. Opportunity is there.
Leonard Floyd, LB (Chi) - From all reports is the star of camp on the defensive side of the ball. Was pretty productive in the sack column last year and has plenty of upside, particularly considering his draft pedigree. I wasn't the biggest fan of him coming out so I'm sceptical that he can produce consistently in a standard league, but it sounds like he's worked on improving his tackling technique and has bulked up as well. At some point you have to take a shot on him on the chance that he can be a Von Miller type.
Ray-Ray Armstrong - LB (SF) - Foster is the hot name right now and yes, he will probably get the bulk of the opportunity at WILB now that Smith is injured, but Armstrong has had some good camp reviews and I think is worth monitoring in deeper leagues, at least until the depth chart and roles are clearer.
Quintin Demps, S (Chi) - Not sexy, but in leagues that start 3+ DBs, he might be useful as depth. Good reports from camp and seems to have locked in the starting SS spot, for what that's worth in Chicago (not a productive position recently). Rookie Eddie Jackson might also be worth watching at the other safety spot.
Derrick Kindred, S (Cle) - Like Demps, the camp reports suggest that he is locked into the starting FS position. That may not mean much, but he's a starter and he can tackle. I'd feel better about him if we knew for sure that Peppers was going to be the starting SS (he should be ), since if he doesn't start over Campbell and Pryor, you'd imagine they'd try to get him on the field over Kindred at the other safety spot, given his draft pedigree.
Bradley McDougald, S (Sea) - Doesn't seem to have a real path to value with Chancellor and Thomas there but I read something about the Seahawks trying to make a role for him by getting all three on the field together. Makes sense since they bothered to get him in free agency, unless they strictly view him as depth. Not high on my priority list, but he's basically getting completely overlooked now. At least we know he can produce.
TJ Watt, LB (Pitt) - Sounds like he's started well, but how much playing time he gets might depend on James Harrison. In the end there may be too much rotation between those two and Dupree for Watt to matter this year, but he's a priority dynasty stash for me in bigger play leagues (and I want him rostered in more tackle heavy leagues too just in case, given his versatility).
