Lets make this so a fifth grader can understand.
If you need to resort to insult rather than answer the questions, maybe I'm not the 5th grader in the argument?
I understand your point. You are saying it is not the best tool to use, but it still is *a* useful tool. You still haven't answered *how* it is useful.
In your example you had two pitchers that looked the same. Their records are 17-9 and 10-13. You get to pick one of them only based on the stats you provided. Who are you going to pick?
The stats I provided were rudimentary. If I was choosing a pitcher, it would be based on other stats. But I can guarantee you wins and losses wouldn't even be a tie breaker.
When you brought up the stat in the first place, you literally explained how the pitcher's record would change based on his team and nothing to do with his performance.
We're gonna keep going around in circles, so I'm gonna bow out.
