Linebackers
Jalen Reeves-Maybin (DET): Could be available in shallower dynasty formats, and worth an add on multiple fronts. First, looks like Jarrad Davis is unlikely to play against the Falcons this week as he's in the concussion protocol. Second, Reeves-Maybin was a hot name in camp and there was chatter that he could supplant Tahir Whitehead as a starter alongside Davis. Look, Davis is a monster, but Whitehead's steady play to start 2017 suggests that two linebackers can produce for the Lions. Reeves-Maybin will start eventually, maybe even next season. Whitehead is a free agent in '18.
Hayes Pullard (SDC): The Bolts love this guy for some reason. Even with Korey Toomer proving he can produce in the absence of either Jatavis Brown and/or Denzel Perryman, they are giving Pullard more snaps than Toomer. Toomer played 27 snaps and produced 6 tackles, yet Pullard still out-snapped Toomer last week. Pullard produced a nice line last week and with Perryman shelved and the Chargers probably struggling to produce wins yet again this season, Pullard could get an extended look if they relegate Toomer to the bench.
DeVondre Campbell (ATL): With Duke Riley's arrival, some dynasty owners may have cut bait with the Falcon OLB. Or perhaps he's rostered but could come with a cheaper price tag. He has had a pretty nice start to the season, though, so you'll have to convince said owner that he'll eventually cede regular work to Duke Riley and Vic Beasley Jr. Takk McKinley will see increased snaps with Beasley sidelined a month, but Campbell may be the main beneficiary stat-wise.
Calvin Munson (NYG): With B.J. Goodson out last week, Munson put up an impressive stat line in the Giants' loss to the Lions (7 solos, 1 assist, and 1 sack). Goodson is set to return, but obviously, the rookie has the chops to produce if Goodson or perhaps Jonathan Casillas on the weak side were to go down. Heck, with the Giants off to an 0-2 start, they may just scrap the season and start playing rookies with more regularity by midseason.
Christian Jones (CHI): Kind of a no-brainer here, but apparently being an inside 'backer for the Bears means you tear your pectoral muscle. With Jerrell Freeman and Nick Kwiatkoski nursing pec injuries (and likely both out for the season), Jones is set to see regular time alongside Danny Trevathan. We know this spot produces so Jones is a must-add in all formats at this point. Jones is just 26 despite what seems like several years of fairly uninspiring play, so there's some gas left in the tank too.
Defensive Linemen
Anthony Zettel (DET): Zettel was on my preseason radar since a few folks thought that Ziggy Ansah could continue his up-and-down play. Well, Ansah had a monster Week 2, but Zettel still managed 3 solos as the third-in-rotation on the Lion defensive line. Definitely a speculative add, and he'd be a DL2 or bye week fill at best, but with the position traditionally fairly shallow, you keep your eye on anyone that shows some promise.
Chris Jones (KCC): Probably already gone in deeper formats, or perhaps someone has already jumped on him after his 3-sack performance last week. But there has been some buzz on Jones for a while now and it's apparent he has a lot of talent. He could be a boom-or-bust type as it appears that his value will be tied to the "big play", but a guy with this much talent should be rostered in all dynasty formats.
Defensive Backs
Detroit Safeties: Honestly, in most situations, I'd say "stay away", but in deeper dynasty formats there are times where you just need to throw some of your free agent cash at a guy and hope he sticks. Your league may vary, but one or more of these guys could be available. Miles Killebrew is the big hitter that could be the big prize eventually, but at this point his tackle totals are low. Glover Quin looks like the steadiest but is 31. Tavon Wilson is still young but is off to a slow start. If Wilson got hastily dropped, I'd jump on him. Or perhaps he's a buy-low candidate in your league.
Justin Bethel (ARI): Bethel is enjoying the fruits of being opposite one of the better shutdown corners in the NFL. Already with 8 solos and 3 pass breakups on the season, he should still see plenty of work with the opposing QB shying away from the other side of the field. In CB-start leagues, Bethel looks like a great weekly play, especially when the matchup hints at lots of passing.
P.J. Williams (NOS): Usually we'd be talking about the rookie corner as being the add, but in this case, it's the corner playing opposite him. Marshon Lattimore has been downright nasty to start his NFL career and is well on his way to being an elite/shutdown type. Williams, as a result, has racked up the tackles. Now, Lattimore is in the concussion protocol and this week's matchup isn't great, so if you're looking for a one-week plug, Williams is probably not your guy. But once Lattimore returns and the Saints start getting some juicy matchups, Williams' tackle totals could jump again.
Eric Murray (KCC): With Eric Berry out for the season, depth charts were filled out with Daniel Sorensen on the strong side, with Murray still backing Ron Parker up on the free side. Well, Sorensen did log 6 solos last week, but Murray also produced. Drafted as a corner, Murray has shown he has the centerfield capabilities and could potentially keep Sorensen in his "utility" role. Given Berry's age and injury issues, the Chief FS spot could be up for grabs in 2018. Watch to see what Murray (and Sorensen) do in a very telling matchup against Philip Rivers and the Chargers this week.
