In.
My thoughts:
Don't use SLG, as it doesn't account for actual time on the field. Total Bases would be better. If you combine it with OBP, you have the two stats for the first rudimentary Runs Created metric.
I think we should go with....
Offense: Runs, RBI, SB, TB, OBP
Pitching: QS, NetSV, K, ERA, WHIP
No to Wins, IMO. Nothing more frustrating to lose in the W category one week because a guy got shelled but got the W because the other pitcher just sucked worse....or, alternatively, because your guy pitched well but the offense didn't support him.
Anyway, whatever we choose, I'm game.
