Try to balance the scoring between OFF and DEF. If interceptions and fumbles cost OFF players -2 points, then they should be worth 2 points for DEF players. If QB loses points for sacks, make sacks worth the same amount on DEF. Otherwise, 1 point for the sack (they also get a point for the tackle). One point for tackles, 2 for safeties, 6 for TD, and 2 blocked kicks.

I've played in IDP leagues where sacks, INT, and fumble recoveries were 4 points each, and it really skews player vaule in favor of defense. You can be kicking a guys ass going into Monday Night when his linebacker has a 2 sack - FR - INT - TD night and your opponent shoots right past you. Don't overvalue DEF stats.
