There are things about a rebuild that you can judge during the rebuild, but to be fair, you really cannot judge it until you see the final product. I think it's fair to say that Terry Ryan is acquiring prospects and not rushing their development, though to an extent he's sacrificing the product on the field a bit, and I don't think that's accidental either. That said, the end result will be what the final product looks like. If Buxton, Sano, Arcia, Meyer, and Rosario turn out to be busts, this team is going to be a cellar dweller for the better part of the decade. If they turn out to be stars, the Twins will be serious contenders for a good chunk of the next decade. Time will tell.
