LB need some assistance

I am in a 10 team non ppr league with any four defensive positions.. I decided to go all LB and here are the guys i picked

L David
Jaylon Smith
Fred Warner
Tremaine Edmunds

here is the scoring Tk 1, ass .05, sack 2, INT 3, force fum 2, def td 6

should i pick up a safety or CB? or pick up any of these guys below and drop any of the four i chose. I want to score as much points every week with the defensive guys or any suggestions of guys i should look for this league.  

Here are a few names available:

Poyer
Fitzpatrick
Kendrick
Isaiah Simmons
Logan Ryan
KJ Wright
Jerome Baker
TJ Watts
Jabrill Peppers
J Bentley
P Queen
Jayon Brown
Alex Johnson
TJ Edwards

LBs are the most consistent tackle producers and you got 1 top 5 and 3 top 25ish. TJ Watt is a MUST add as he has top 5 potential and top 10 consistency. If you can carry more than 4, pick him up now and hold the rest.  If not I personally would recommend dropping Warner or Edmunds, preferably Warner as he is currently on the COVID list. ADD TJ WATT IMMEDIATELY!!!

I'm in a more in depth IDP league so I'm not as familiar with these lower scoring settings. TJ Watt gets sacks yes, but he lags way back in tackles which are more consistent production. He's a feast or famine type player.

I'd prefer a steadier player with tackle volume and the occasional big play.

Jayon Brown or Jerome Baker should step up this year and so I'd prefer those two but I'd also prefer Queen's upside or Poyer's consistency over Watt with these scoring settings.

Now that Warner is off the Covid list and ready to play in this scoring setting he is a must especially with 49ers so many injuries.

Would you drop Edmunds for Baker or Queen or just keep Edmunds.

I'd drop Edmunds for Queen

Thanks guys for your advice, this really helps
