2017 Topps Baseball Forum

For most of my life, I have been more of an NBA collector vs MLB, but I have recently found enjoyment in once again collecting MLB cards.  Maybe because I am not too familiar with how Topps does their baseball sets, but how do they choose who goes into what series release?

Like I know my Dbacks really stink, but I was a little let down to see there is no Zack Grienke or AJ Pollock cards in the Series 1 checklist.  Hopefully I will at least pull a Goldschmidt from this set.
