Hat tip to MLBTR, again the best off-season resource around, ESPN.com's Keith Law sat down with another one of my favorites recently; J.C. Bradbury and the interview even included a Rays mention:
Which organizations have the best and worst farm systems in baseball?
I haven't looked hard enough at that to answer it, but I'm pretty sure I'll rank them all again in January. I can say that Tampa Bay and Texas are the clear 1-2 to me right now.
You would figure that crown would go by the waist side after this year with Evan Longoria and Jeff Niemann likely graduating, although with guys like Desmond Jennings breaking out and another top draft pick joining the ranks, who knows.
