Most likely number to be re-issued in Colts Football Posted May 2 I am not a fan of permanently retiring a #.....however, Hall of famers with long and storied carriers should be honored. I wish we would set a time period for players jersey numbers we hold with high esteem. So for instance a 20 year period for say Manning's #18. That length of time would honor who he was and what he did for the remainder of his generations fandom. 20 years removed new generation and the chance for someone else to build a storied carrier in that #. The practical side to this kind of approach there are only 99 Jersey #'s and team size, will probably only grow if they successfully add more games to the season in the future...pretty soon the math wont work if you keep setting aside #'s for all eternity.
