The commissioner of my league announced that he is going to a 6X6 format next season and will replace the Wins category with QS and K/9. I am going to assume that ERA and WHIP correlate fairly well with QS, although there may be exceptions. For instance, a pitcher who throws 8 QS but gets blown out in 2 disaster starts may have an inflated ERA relative to his QS's. What QS's will do is give credit to the pitcher who has a good start, but fails to get a W because of low run support or a Blown Save. QS may be less of a crapshoot than W's, but using Dominant Starts or some sort of Game Score metric would probably do a better job or rewarding very good starts and penalizing bad ones. Here is a list of all 2016 SP's with 100+ IP in order of K/9 with their ERA. If you can find a correlation between K/9 and ERA, you have a better eye for pattern recognition that I.

Like I said, if you can see a pattern here, you are much better at pattern recognition than I. So, what drafting strategy will I employ in my league's new 6X6 format? I believe that WHIP correlates better with ERA than K/9. I also believe WHIP is more stable over time than ERA. So, if I continue to load up my bench with SP's who have a low WHIP and rotate them into the starting rotation with daily lineup resets, I can rack up QS's and K's while still winning a majority of WHIP's and ERA's. In a 6X6 League, you can better afford to punt one category, so fill RP slots with relievers with high K/9 regardless of Saves. The other strategy would be to punt W's and K's, spend all your allotted pitching dollars on a few ace SP's and then load up on relievers which would give you K/9, ERA, WHIP and Saves.
