Possible Trade and WDIS? New to IDP

New to IDP, we start 3 positions with LB's seeming to be the most important. I have Laurinitis, D. Smith, J. Freeman, and J. Allen. 2 questions, would you drop Allen for Deandre Levy? Also, would you trade Laurinitis for Bobby Wagner. Kiko Alonso, or Perry Riley?  After seeing how STL distributes tackles at home this season, it is very discouraging.

Thanks in advance!
