Craig, thanks for the link to the Brodkowski/Callis video and article.
Who the heck knows which players will get injured, have personal problems and/or just fail to progress for some other reasons?
However, both Brodkowski and Callis are extremely knowledgeable about this topic and the article is worth a read.
It was great to hear them talk about Jackson Ferris, Drew Grey and Daniel Palencia as high-upside guys.
Let's hope more than 1 of these 3 young pitchers ends up staying healthy, continuing to develop and pitching well for the Cubs!
