Deion Sanders issue was not with Gurley himself but rather the Atlanta Falcons for allowing players to continue wearing a number he wore for the five seasons that he was with the Falcons. The problem with this announcement by Deion is twofold.
The first issue is that the Falcons decided a long time ago not to retire jersey numbers and stopped doing so. Instead, they started the Atlanta Falcons Ring of Honor is pay tribute to those that have meant a lot to the organization. Deion is, of course, part of the Ring of Honor.
The second issue and the biggest one, Deion Sanders does not deserve the distinction of having his old number retired in Atlanta.
