Maybe so, but as the last arm his presence matters and can help off the field. He's pitched in 9 different post-seasons.
In a positive blow out he can eat a few.
I've grown oddly comfortable with Kuechel making the postseason roster. I don't see a place where he would be my first choice, but I see a lot of places where it might be nice to have him.
Why? When he's available he can run. It's the next day that's the problem. This is the playoffs and he probably hasn't had his last shot (of cortisone).
