I'm coming into this pretty late, but hey...a lot of players have worn numbers that were retired after the player who the number is retired for played. See this website http://ignarski.tripod.com/temprost.html #26 was worn by several players before it was retired. Same with #10. I think the reasons 14 and 23 were not reassigned were because Ernie was such a legend when he retired (and he retired as a Cub) and Sandberg stayed in touch with the organization after he retired for the last time. When Kenny Hubbs was killed, the Cubs said they would not issue that number (16) again, and they kept their promise until for about 7 years, and I know people who to this day think 16 should be retired for Hubbs. In my opinion, before Sammys number is retired, the Cubs should honor some of their old time heros. Stan Hack, Charlie Grimm and the biggest oversite, Phil Caveretta.
