Trying to avoid making it a direct who do I keep post, but what the heck - I'll skip DL (have Young and Hunter, only need to start 2, so will probably just keep those 2 and pick up a hot hand for bye weeks) and DB (I have hot garbage there, but doesn't score well so I'll keep a couple and pick up hot hands).
For LB though, my active roster is Fred Warner, Bobby Wagner, Tremaine Edmunds (my likely starters) with Alexander Johnson and Neville Hewitt (though may cut both in preseason to free up roster spot). May also add Jermaine Carter depending on waivers tomorrow.
Possible DTS guys at LB (we can keep guys on DTS up to 3 years if placed there as a rookie) that I have are: Derrick Barnes, Alex Highsmith, Tanner Muse, Joe Tryon, Josh Uche (and possibly Jermaine Carter depending on waivers tomorrow). Ideally I'd trim this to 3-4 of them, but if compelling enough cases can be made, I could trim some from the offensive side.
Right now, Barnes and Highsmith I think are for sure holds, and Tryon seems to be doing well enough on the field that he is probably worth holding. I can probably easily find an additional player or two on the offensive side to cut if either Muse or Uche have the upside to be contributors, otherwise I think I'm better off with the RB/WR dart throws.
