Dynasty League Linebackers

I am currently in a dynasty league with 3 IDP slots.  Tackles (solo & assisted) are 2 pts for each.  I drafted Logan WIlson (Bengals) & Kenny Young (Rams).  Are they worth keeping or should i dump then for other players?  I drafted Wilson cause everything I was reading stats he will take over as the season goes on.  Young was my whim draft, since the Rams starting linebacker job was anyone's to win.

I also own Kendricks (Vikings), Walker (Colts), Bostic (Washington), Davis (Lions), & Hewitt (Jets)
