Benny Bengough and Andy Pafko - number 1 cards in two of the most popular sets ever.

Also maybe Ray Chapman - only player ever killed from playing baseball.

Bill Wambsganss - only player to ever have an unassisted triple play in a world series.

John (Jack) Graney - supposedly first ballplayer to become a baseball broadcaster/announcer.

Earle "Greasy" Neale and George Halas - both famous, but not for baseball.

Moonlight Graham - for obvious movie related reasons.

Dave DeBusschere and Danny Ainge - basketball stars.

Jack Kemp - politician. (Strictly football though.)

Johnny Berardino, Chuck Connors, Joe Garagiola and Bob Ueker - later on TV or announcer fame?

I'm sure I'm missing others. There are some other TV actors from football I'm forgetting, like Fred Dwyer.
