Everyone's free to use their own starting point. However, if you want to start it when Ryan arrived, or even last year, we should really only be talking then about what he's done since that time and not before. And frankly, he hasn't done as much, but he's getting a ton of the the credit for a farm system. 2012: (+)Drafted Buxton. No doubt this was a great pick, but almost any pick was going to greatly improve their farm system since they were picking 2nd. 2013: (+) Meyer, May, Cole Stewart (-) Span, Revere. Definitely a trade that should pay off, but both Span and Revere were young enough to be part of a rebuild and their departure looks to have left what may be at least a 1-2 year hole in CF and at a clear cost to the major league club. Frankly, I don't know how much hope we should have for May to be a significant piece. The rest of the bunch that looks to be a significant part of the rebuild had very little to do with Ryan. Sano, Rosario, Arcia, and Pinto, and only the latter two have tasted the big leagues at all. So, in total at best, he's drafted two promising players and acquired one other via trade at significant cost to the major league club while the rest of the rebuild were brought in under different leadership. If you take away the draft picks as completely his (because a high level of talent would have been added to the farm system regardless of who the GM was with two high picks), I think you're left with one promising young pitcher as the only current gain in the rebuild. Meanwhile, the big league club has gotten worse.
