Is there anywhere to find IDP Flex info?

My league starts one DL, one LB, one DB, and three IDP flex spots. Would you ever start anybody over LBs in the flex?

 I have JJ Watt as my only DL. I have Kuechly, Wagner, Ogletree, Burfict, and Kwon Alexander at LB. I have Landon Collins and Rashad Jones at DB.

It is a 12 team league, I'm pretty sure no one else is aware of the Guru. I know I'm stacked on D, but have to make up for some O weaknesses. Bosa is on the waiver which would cover me for all bye weeks. If I roster 2 DLs and 2 DBs would you ever use them over the quality LBs I have?

I know to value DL at draft time, but I can't find a place to compare the different positions in the flex on a weekly basis.

Thanks in advance!

Hey Shep. There is no better IDP position than a quality MLB or ILB assuming that you have a standard scoring system and not a system that weights picks, fumbles or sacks more than usual (2 to 4 points each). DBs will occasionally go off and outscore LBs, but not on a consistent enough basis to play them over LBs.
