I don't care for IDP scoring that's balanced across positions. What are you trying to do with it - honest question. My guess is that you're trying to give people a reason to roster 3-4 DEs and OLBs. In my opinion, a better way to that is just to use an Edge position. Ideally, you would have:
- DL: 3-4 DEs, 3-4 NTs, 4-3 DTs
- Edge: 3-4 OLBs, 4-3 DEs
- ILBs: 3-4 ILBs, 4-3 LBs
- CB and S unaffected
A couple of sites offer Edge right now (ESPN, Fleaflicker), and based on an interaction with Gary Davenport from FantasySharks, who sets MFL positions, I'm guessing MFL will offer that soon as well. Right now you could use a tool from Adam Tzikas to convert an MFL league to use Edge.
The reason I prefer that approach instead of tweaking scoring is that some of the positions are just so random. If you juice DT and CB scoring, they're still just as unpredictable, and teams will end up with polar scoring of either 0 or 20 from each of their DTs. They might average out to have similar scoring averages as the other positions, but I don't really see how that matters. It's not like we balance QB vs. TE scoring on the offensive side - their value is defined by VBD, reliability, and longevity (if dynasty).
