Firstly, my 12-year-old brain is dreaming about Andrew Vaughn blossoming into a stud that signs a long-term deal and bats cleanup to the tune of .310/.370/.490 like many here.
But his underlying skillset has inoperable flaws, namely defense and baserunning. He's not going to win any gold-gloves, and he has 3 stolen bases in 625 major league games.
For him to be a true, first-division regular at first base, he'll need to mash.
With that said, perhaps Andrew Vaughn, the 3rd overall pick, can actually mash. I think that most of us, with confidence, see the White Sox as a moribund franchise. A comparatively lousy, old stadium in the other half of a big city that invested in a bunch of talent without any baseball character. Now I don't know Vaughn, or what makes him tick, but it's quite possible that he hates losing so much that his big-league dreams were DOA in the Southside. It's possible that the organization and Vaughn were never on the same page with how he should develop. Perhaps he was being pressured to produce RBI in Chicago and encouraged to swing at bad pitches? Perhaps he never had the confidence in their development to listen to his coaches over there and therefore he was sent a reality check that hit home.
His draft profile was remarkable to me at the time, in terms of his hitting ability. I couldn't believe that a DH was going to be drafted top 3. But that's what nearly every scouting outfit said... that his bat was that special.
