I think it's silly to take 2015 Lester over any of DeGrom, Syndergard or Harvey. But that's as may be. I'd certainly take those three over or Hammel or Hendrcks or Haren.
I think the best hope for the Cubs is that Harvey is simply gassed, and one or more of the other three kids crumbles under pressure. I see this as a 50-50 series, really - it's true, you can't get to the NLCS and not expect to face a good team. It's choose your poison.
If nothing else, this represents a fascinating clash of two different developmental strategies. And proof that they can both work.
