Well, the BA PCL top 20 prospect list is out. But there are no Rangers on the top 20 list, so who cares...
Of course, Jim Callis did do a chat session where he said Ian Kinsler, Jason Botts, and Adrian Gonzalez all would have made a top 30 list, if they went that deep, while Gerald Laird had too many big league ABs to qualify for the list.
21-30 seems like a reasonable range for those three.
