Maybe it's just me but I thought it was kinda interesting how their top 10 breaks down. The first four are the older prospects that should be up within a year or a year & and a half.
Yonder Alonso - 21
Todd Frazier - 22 (turns 23 on 2/12)
Drew Stubbs - 24
Chris Valaika - 23
While the remaining six are the (younger) players that have eta's that are farther off.
Yorman Rodriguez - 16
Kyle Lotzkar - 19
Neftali Soto - 19 (turns 20 on 2/28)
Juan Francisco - 21
Juan Duran - 17
Devin Mesoraco - 20
Seems like at least a few of them (Yorman, Duran, Mesoraco) could be on this list for awhile.
