I think you're drawing a ton of conclusions based on pretty simplistic logic, but we'll see how it all pans out.
Harvey showed Ace like ability in albeit limited innings this year.
I know teams will make adjustments but this kid is the real deal. I see him being a 15 game winner by 2014.
Wheeler has all the ability in the world, if he keeps his control in order there is no reason why those two couldn't anchor a very good rotation and very quickly with the pieces that are already there.
As for drawing a ton of conclusions well that's the prospect business in general but these guys seem like they come as advertised much like Wright and Reyes were when they came up.
