Any IDP players on here? could use advice, its my first year

So my league replaced Kickers for 1 IDP. Any position can fill the slot (DE, LB, DB)

With that said it seems that LBs score the most points on average. My plan was to stream the position, so is there anything you look at when making your pickups.

Smartest thing seems to be, find out what teams rush up the middle the most and get the opposing MLB. Good idea?

I just lost DJ and woodhead so im looking to get my little wins at every position possible. So defense and IDP will matter big time for me

Any suggestions are appreciated, thanks guys
