I think the philosophy did change somewhat. There has been a more consistent focus upon college players with the top draft picks, while actually picking up as many or more H.S. fliers with later picks -- I think a realization that most of their first and second round H.S. draft picks had been little more than fliers. Yes, he took Randolph and, I guess, Moniak -- although that was really Gillick.
I agree that our international operation, especially for position players, continues to fall short. Sal found Ruiz and he has done well with actually quite a number of low-cost pitchers. We have Realmuto as our starting catcher. Whether he stays healthy enough to make his mark in the majors or never gets there (and he's knocking on the door, pitching well in AA), Realmuto means that Sixto has already made an MLB contribution.
I don't know how our international operation works. Is Sal doing a lot of scouting, or has he become more administrative? The later Arbuckle years, until management asked him to become more directly involved again, went downhill as he left more of the scouting work to others.
