Don't blame Gary. I used to do the same - and believe me I don't understand some of the changes he pushes - but he's between a rock and a hard place with these positional designations. I know he knows that in existing leagues that are tackle heavy, moving those DEs to LB can ruin a player's value and he's reticent to do that. Team and online depth charts are fairly bullshit when it comes to designations in today's NFL since players line up in different spots, rotate pre-snap, etc. to try to keep offenses guessing. I get the Neal point - is what he's going to do this year so much different than what he did in Atlanta? Probably not other than he goes into the linebacker room for meetings vs. hanging with the safeties and DBs.
Honestly as much as I swear by MFL, whoever Gary is advising at MFL about default designations needs to listen up. Long-time existing leagues just aren't going to use Sticky's tool or manually switch players - edge and IDL positions are going to have to be made the default. I'm in a ton of these leagues where commissioners just won't make that flip because they don't want to be blamed by owners for impacting player values.
