His ERA in the Cape Cod League was in the 4's- for those of you who are 90%ers, keep in mind that this is a wood bat league that we're talking about here.
He is simply a guy that can throw really hard and has a good slider. He was that way in high school. But, he pitched at a small school that was not very good. He could blow away people in 2A high school baseball, but once he got past that- he never could put it all together mentally.
If Devin Jones had, say Caleb Reed's head on his shoulders, he would be All-SEC at worst.
