1) I consider the Dodgers more dangerous to baseball, not AS MUCH because of the free agent spending, but because they seem to be a desired destination for Japanese players. Before you start a "why shouldn't they" argument, that's why we have an amateur draft, and international spending limits, so that all the best players can't just sign with the Dodgers and Yankees.
2) Kim and Sasaki aren't "rookies". You don't generally act impressed with starting pitchers who wind up in the bullpen because they couldn't dominate as starters. Why should that be different with other teams?
3) I would expect a team that is the greatest in drafting, signing and developing players to have more than 2 home grown players in their lineup, and any of their main starting pitchers to be home grown. I understand that they traded from their own farm system to acquire Betts, Edman and others, but that also highlights the folly of ranking systems. Nobody from the Betts return is a significant producer. Vargas in still a work in progress.
Michael Busch might be the best prospect they traded in the last 10 years. For every Corey Seager, there's more Joc Pedersons, guys who are just slightly above average regulars. That's great, teams need them, but every player coming out of the Dodgers' system isn't at the level of the best position player they produced in the last couple of decades.
I understand that an important function of a farm system is to create players other teams want, regardless of what they become.
4) Dustin May and Tony Gonsolin aren't part of any collection of anything right now. May was a nice prospect who never had sustained success, Gonsolin had one nice year, and is yet another example of how the Dodgers chew through pitchers like rats on your asbestos siding. Kershaw was drafted 20 years ago and isn't indicative of what is going on with the Dodgers right now, just as Chris Sale isn't an example of the current White Sox development apparatus.
