Alright, let's think about this.
First thing that pops out at me is a SAVE is 10 pts., a BLOWN SAVE -10, a WIN is 10 pts., and a LOSS is -10 pts.?
Right away I figure elite RPs are WAY more valuable than any starter.
Top SP Verlander - 24 wins (240 pts) 5 losses (-50)
Top RP Kimbrel - 46 saves (460 pts) 8 Blown Svs (-80)
I also wouldn't concentrate on shutouts or complete games, those are now considered "fluky."
The wlks/strikeouts ratio is considered already in every fantasy ranking procedure so you can ignore that. (In other words, you already want high strikeout, low walk guys, we all do)
And then holds are 5 pts. so you need to go to specific web sites that show you "HOLDS' rankings.
Also, remember that after you go high on the elite RPs, you need to settle down and bump up SPs who play on good teams (WINS being +10 and all) Also, I would LOAD, and I mean, LOAD my bench with great middle men who have a chance to become closers.
And guys like Farnsworth (all RPS) need to be bumped up in your rankings.
Of course, the importance of pitchers as a whole group may pale .... I have no idea what your hitting settings are.
