I kind of like that these guys are both 2017 draft picks for two reasons.
1) To build a sustained period of success, the Twins are going to need another group of prospects to take the places of this group once they graduate to free agency. We got to experience that in the '00s years, when Mientkiewicz, Koskie, Jones, etc were replace by Mauer, Morneau, Cuddyer, Kubel. With some high end talent banging around in the lower minors right now, like Royce Lewis, there's hope that the Twins could see a similar handoff from this group to another group. This adds to that chance.
2) So far, this front office looks pretty astute at gauging draft prospects (knock, knock). Royce Lewis looks tremendous. Rooker is obviously pretty exciting. It stands to reason these were guys that they liked but missed out on and have continued to target.
I agree with #1 - if the new FO can keep the window of opportunity open it'll be because they were able to bring up another wave of prospects like Ryan was able to do.
But #2 - we're too far away from having an idea on that. Yes the draft looks good but these kids have been playing ball for 3 months. Way too early to determine if they drafted well.
