Billy is the lone Cub among the fifty players in this set that made an instant impact. Winning the 1961 Rookie of the Year makes it hard to argue that he didn't have an instant impact.
It's shocking, though, that Kris Bryant wasn't on the checklist. He too was a Rookie of the Year, and he also was an All Star his rookie year. Topps always keeps you guessing, don't they. Keeps me scratching my head, too.
The set has several parallels and I'll be chasing them for the Billy Williams collection. Stay tuned for more.
