In a S3F article "Pocket Aces" written by our talented Porter, it gave options as to who you think is the best 1-2 punch in the rotation. I picked Webb and Haren as a no brainer. Now I have to change my mind after I read this from rotoworld.com.
A very interesting tidbit on Haren if I do say so my damn self.Dan Haren (SP, Arizona Diamondbacks) – Moving to the weaker NL will give Haren a value boost, but he'll miss the vast foul territory in Oakland and figures to see his ERA jump while going to one of baseball's most hitter-friendly environments in Arizona. Consider that Haren has a 3.43 career ERA in Oakland, compared to a 4.11 ERA everywhere else, and you may think twice about betting on him to compete for another ERA title this year.
