I know it was an off-the-cuff response, but here's a glimmer of hope from today's Keith Law chat:
Jim (LA): Name your top 5 minor league systems.
Keith Law: (2:12 PM ET ) #1 is Tampa. #2 is Texas. Beyond that I'm less sure, having not done this as a serious exercise (I will in late January). #3 is probably the Reds - very top-heavy, but tough to ignore that much star potential. #4 Boston. #5 ... I'll say the Giants, the opposite of the Reds, lots of star power that's years away. I reserve the right to change any of those last three.
