This tradition of mine is going to be ending within a few years however, as BBM hasn't done a new Tokyo Big Six set since 2013. Unless they start doing them again (or one of the other card makers picks it up), the draftees are going to get sparse pretty quick. The final 2013 set features no freshmen, so next year will probably be the last post like this I do.
Only four Tokyo Big Six players got drafted directly out of their colleges today. There may be former collegiate players drafted out of the industrial or independent leagues today but I wasn't able to find anyone who had a card.
