Yep, which makes it all the more interesting that old-school READREAD nailed this one while the SABR-guys on the board whiffed. Just an observation.
The SABR people never rule out luck. Luck can last an entire season. Stats can indicate one thing and for a period of time a player can outplay his past.
But the reason I love stats, the law of large numbers, and all that jazz is that when you look at a large sample size (5 weeks of Cliff Lee's magical singing road show is not a large sample size) Cliff Lee will be Clliff Lee. It can't be otherwise. One poster said it best: there's was nothing to ever suggest he was this good, meaning pretty much just that. He isn't.
I guess he could have developed some new pitching style, but a 19.5 KK/BB ratio is not sustainable (in fact it's already fallen from that, I believe).
5 weeks of box scores do not anoint him as Cy Young.
