So I'm trying to figure out which of these stats best correlates to wins in the leagues. My first thought was PA would be worth looking at, and most of the teams doing the best are in the upper third in PA (jbohrman a very notable exception). It appears not taking too many IP also helped, which makes sense because you'd be reducing the quality of the innings you paid for and didn't need.
All of this comes back to making me wonder how important being able to manage fatigue is, and having the experience of doing it enough to avoid any wasted salary can make a massive difference. I took the 4th-most PA, clearly concerned about excess fatigue from all the scoring. My offense is doing fine, but if I'd been able to make my pitching just a little stronger by saving some of that money ...
