Andrew Vaughn won the Golden Spikes award for the best college player. Here are the past winners before him:
2016: Kyle Lewis (ROY)
2015: Benintendi (eh)
2014: AJ Reed (Ouch)
2013-2001: Kris Bryant (great), Zunino (fine), Bauer (great), Harper (great), Strasburg (great), Posey (great), Price (great), Lincecum (great), Gordon (great), Weaver (great), Weeks (good), Prior (great)
All in all, the vast majortity of the people who won that award went on to be very very good/great MLB players. Not sure why so many here have practically given up on Vaughn (yes trading him for Bassit/Gray is giving up on him).
