I think BP took the bigger picture view and didn't factor in performance in 2014 as highly as some of the people on this board did. I remember listening to a podcast with Jason Parks and he was still really high on Tirado even though he wasn't performing well. Some of these really young dominicans can have a huge culture shock living in cold weather places like Lansing and it can set them back, but they are so young and the stuff is still really good that they are still good prospects.
Personally, Id have Tirado lower and guys like Travis and DSJ higher but its just opinion really. I see some of you having Borucki pretty high but reports on him say his FB is 87-88 with an average curveball really being his only decent pitch. Numbers in the minor leagues can really be misleading sometimes.
