Vontaze Burfict Cin - Good add for your team but suspended for 2 more weeks. Top 5 potential from there on with high chance of furter suspension due to noodle brain. TNF game means you have to wait until waivers next week, anyway.
Malcolm Smith SF - Watchlist. He didn't play last week, doesn't look great for this week and may lose spot to Warner/Foster once Foster's 2 week suspension is over.
Rashaan Evans Ten - Massive upside. Should start this week after missing week 1 to injury. Tough to put into starting lineup this week but if you don't grab him now you'll likely have to use a bid/claim on him later.
Mason Foster - 70% of snaps lead the team defensively. Good add compared to OLBs on your team.
Look for:
Fred Warner - SF LB - Huge week 1 so you probably missed the boat already.
Kenny Young - BAL LB - Mosley could miss a week or 3, Young looked great last night. TNF game means you have to wait until waivers next week.
Kyzir White - LAC LB - Snap count is likely to rise and seems to be starting over Jatavis Brown.
Dee Ford - KC - Watchlist? Not ready to beleive he doesn't suck still but 89% of snaps puts him in 3 down LB territory.
Eric Berry KC - Good add, great safety. Injured last season and missed week 1. Currently at risk of missing week 2 so if you don't have roster space you may have to wait. Definite upgrade to your DB squad and has top 5 potential based on talent, experience, and a weak looking D overall that should make most KC games shootouts.
D.J. Swearinger Sr. - FS but he is actually a pretty consistent scorer for FF purposes. Good add, as is his SS counterpart, Montae Nicholson. I'd take the SS when possible and wouldn't want both but they are both at 100% of snaps.
Chris Conte TB - Better than carrying a CB but total JAG that belongs on the wire.
Markus Golden Ari - Injured last season and hasn't quite made it back but should be a decent add once he's playing again.
Not liking the rest the DT/DE list you posted. Maybe someone else does... I'm notoriously bad with DE and am always churning through the waiver wire fodder.
Recommendations:
LB: Add Rashaan Evans TEN / Duke Riley ATL / Mason Foster WAS (drop Ragland / Reddick / Houston)
Keep Williamson and Collins. Foster & Collins are both droppable for guys like Young BAL, Warner SF, Burfict (if room / after susp.), and Kyzir White if his snap count climbs as some of us here expect.
DB: Add DJ Swearinger WAS / Montae Nicholson WAS / Eric Berry* KC *if playing or roster space allows. (drop Quin / Slay / Gilmore)
DL: Keep Donald / Harrison / Suh until Golden is ready to play. Or follow someone else's instructions that does better with DL than me.
