Talk about an open ended question.
What is the make-up of your league? Are guys serious, do they have a great sense of humor? It's hard to come up with a name without having a feel for the league. Since you are a Packerbacker safe suggestions could be:
The Green and Gold Division. May go with either Green or Gold.
Brett Favre Division.
Bart Starr Division. Old School
Curley Lambeau Division. Real Old School
Moe, Larry and Curley Division
The Last Place Team in the NFC Central Division (Sorry, as a Lions fan I cannot resist)
And my fav: Shoulda taken Barry Division.
