These threads are about the strengths of the organization as a whole at the various positions, not the current strength of the major league team. I agree grades should not be “completely” based on players in the minors, especially ones who haven’t played an official game above low A. But the guy was considered to be the easiest 1:1 choice since Harper. That’s not nothing.
There's the matter of being the 21st pick and not 3rd, but if DL Hall could be in the ballpark of where Ian Anderson is now in a year, that would be nice.
Scanning the 2017 1st round if we re-did it today, I see Lewis, Gore, Hiura, Adell, Ramos and Pearson as guys you'd probably obviously prefer to him.
Hall head to head with the Shane Bazzes and Clarke Schmidts of the world will tell us a good deal of high in the league the peak Rutschman teams can get.
