By the time their "value may increase" it'll be wasted time, burning more of Steph's prime and this core's window. Case in point: Wiseman; just look at where his value is, at the moment. He went from being gassed as the next DRob to now looking like JaVale McGee with Penny Hardaway on speed dial. And if the Warriors are giving reps to Wiseman, Moody and Kuminga, chances are they're not going to be winning on the regular to even raise their value.
And I don't even disagree with who they drafted, because it makes sense as they both were essentially BPA, but it's painful to see what will be essentially the same makeup of a roster heading into next season.
