It's just 2 defensive players, any position (so pretty much LB and safety), the offensive scoring is standard, and theres also team defense. Here's the defense settings:
Tackle Solo 1
Tackle Assist 0.5
Fumble Recovery 2
Defensive Touchdown 4
Taking a glance, even the best defensive players last year (Patrick Willis, D'Qwell Jackson, Beason, Weddle, etc) only scored in the 130s. So they score less than the best team defenses, and less than your kicker, but you do need 2. So I'm thinking pick them after one of the elite defenses, but before the middle of the pack ones, but near the end of the draft, right?
Also, if anyone knows any good IDP rankings that'd be nice
