I saw BA's top 20 prospects and didnt see Delin Betances.  I am really intrigued by him and was wondering if anyone knew how he was doing this year.

Also, I read this about Kyle Drabek and Kasey Kiker.  Kyle Drabek "the Woodlands (Texas) High righthander Kyle Drabek has as much pure physical ability and aptitude as anyone...he delivers a mid-90s fastball and two quality breaking balls with ease...Kasey Kiker of Russell County High (Seale, Ala.) has arguably the best raw arm strength among prep lefthanders. He regularly hits 95-96 mph for the defending national high school champions."

So they are really talented.
But what is alarming is what I read afterwards, "Yet Drabek and Kiker may not go as high as their talent alone would warrant. Scouts have expressed worries about their makeup, both on and off the diamond."(Drabek) will still go in the first round . . . but you better do your homework on him. Kasey Kiker, too," a second AL scouting director said. "On the mound, they're both top 10 picks. But with all the other stuff, it's hard to pick those guys."

Does anyone know what those scouts are referring to??  And how much should or does a prospect's makeup affect him?
