Just because a team doesn't accomplish much, doesn't mean the player didn't.
he was here 7 years and had over 1000 6 times. (and 90 touchdowns)
it'll never be retired
edit: (adding more), although moss is an extremely talented player and a terrific entertainer, he never did much for the actual organization. yes you can argue he brought us some popularity with the throw it up offense they showed off, but those were mainly bandwagon fans that stopped watching when we'd lose and/or traded moss. yes we went 15-1 his rookie year, yes we made it to the NFC championship, but we never really accomplished much if you think about it. ecspecially with all the pooh he caused the front office, they'll never retire his number, if he would have played longer here and changed his attitude (to about what it is now), you best your jiggly butt it would have been retired
