A discussion of the top five players who are not valued sufficiently by their organizations. It's written by Paul Swydan of FanGraphs. Patrick Corbin is one of the five: "Patrick Corbin, P, Arizona Diamondbacks "Last year, Corbin turned in some fairly solid work as a rookie in the Diamondbacks' rotation....it was Corbin who provided some stability to the back end of the rotation.

Since there has been a lot of discussion about him here, I thought I'd mention that Profar is on the list of prospects.
