Guys, don't bust a nut just yet, first of all, this is a RULE change which requires league owners votes (2/3ds by the way)... which don't "just happen"
Also, ESPN also reported that they jumped the gun on this...
Uniform numbers rule change may not happen until next season
Tue, 16 May 2006
Updating a previous ESPN report, NFL spokesman Greg Aiello said Monday, May 15, that there still was a possibility the league's uniform number rule could be changed by a vote of owners at a meeting this month in Denver. The competition committee will issue its report on the matter to owners at the meeting. It would take a two-thirds vote of the league's 32 owners to change the rule.
Also, this again isn't just about Bush, its about numerous players that have requested waivers over the years and have been denied. Bush has already been told that he will NOT receive a special waiver to wear #5 and will only be able to wear it IF they Owners pass a rule change. This rule change would apply to all players in the league, not just Bush.
