That just shows how much of a crapshoot the draft is. Pick any random team and a random year and the results are usually pretty pedestrian. Here's what I did just now on BR, all random, the best player picked:
2013 Astros - Tony Kemp
2010 Twins - Eddie Rosario
2015 Rockies - Brendan Rogers
2012 A's - Matt Olsen (good pick, #47 overall, comp pick for losing DeJesus)
I think our old friend Biggs was right with his theory that if you can get a Tony Clark in your draft then it was a very good draft. He wasn't anything special, solid player but that's about all you can hope for. Not every draft has a franchise player like a Trout or Verlander or ARod.
