I have seen things saying potential top high school pitcher who fell because of injury- nothing putting him in the category you have him in, maybe your list of not as goods means good pitchers take longer to show themselves and drafting out of college is the better route?
It certainly could. I think Rizzo and many others prefer college pitchers. I do too, on the whole.
I'm not saying Giolito will be as good as any of those guys. All I am saying is he has been given the gifts to be better than any of them. He has to stay healthy and work hard. My main point is that when you have a chance to get a guy like this, especially when it looks like you'll be picking at the bottom of the draft for awhile, you have to go for it.
