You can make a lot of cases that you can take the win stat out of the game and you can still figure out who the good pitchers are, and I agree with that to some extent. But there's something about your win-loss record, there's something about having wins by your name that means something. Regardless of how important that is.
You never want to be in a defensive mode or have a defensive mindset. You always want to know that you're in control as the pitcher, you make him get hits, you're never passive, always aggressive. If I get beat, I want it to be because I got rocked, got hit hard, never because I walked a couple of guys and before you know it.
