Ogletree, Alonso, Preston Brown, Jordan Hicks, Sio Moore

I'm new to the IDP thing so I need advice.

Scoring is 2p for tackle, 1p for assist, 1p for sacks

I have Ogletree, Kiko Alonso, Preston Brown, Jordan Hicks and Sio Moore.  I start 2-3 LBs a week.  Is this good enough or should I try to trade for a top tier LB? (Like David, Bowman, or Kuechly)

I think Ogletree and Brown are you absolute locks every week with that tackle heavy scoring system. Alonso, Hicks and Moore are pretty decent bench players too. If Moore continues to rack up tackles like he did last week (which I think is a real possibility and that's coming from a Colts fan) then he could be a stud for you.

I don't think you need to trade at all.
