I kinda get it with Conrad vs. Ballesteros, since Mo comes with prospect fatigue and it's easy to see him as a DH only guy, and Conrad would have likely been a Top 5 pick in the most recent draft if he were healthy. I don't agree with it, but I can see it.
What I don't get are Hartshorn and Wing. Don't get me wrong, I like them both, but they were high ceiling high school prospects who are a long, long ways away. Cripes, Wing is still relatively new to pitching. To me, you either have to be extremely high on both, or have a very, very negative opinion on the Cubs' system to rank them that highly.
