SAN FRANCISCO -- There will come a time, maybe five days from now, maybe three weeks from now, maybe seven months from now, when Clayton Kershaw will struggle. It happens to all of them, even to him. It's not hard to imagine; it's just hard to remember what it looks like.Of all the things to marvel over in this season for the ages -- and the statistics alone speak to it so poetically -- it's the ridiculous consistency, the redundancy of his dominance, which has been so extraordinary to those who have been around it every day.
