I'm wondering if anyone has experience with leagues using defensive categories. If so, what do you use? What works well, what doesn't?
It seems there's some symmetry in an old-school 4x4x4, using ERA/WHIP/W/S for pitching, Avg/HR/RBI/SB for offense, and PO/AST/DP/Pct for defense. I'd restrict rosters to at most one per position (no utility slots), but I'm sure there are other ways to play.

Remove positional eligibility altogether (i.e. all offensive players are Util), but giving players credit for playing games at harder positions: 1 point per game at 2B/3B/CF, and 2 points for SS/C.
What variations have people tried, and what do they like?
