I guess when it comes to perennial winners who are we talking about?
New England -- A bunch of Super Bowls that are questionable due to cheating.
Pittsburgh -- Quite a few people respect them and their franchise, recent Super Bowls seem to have had some gift calls go their way.
Dallas -- Annoying fans. Annoying owner.
Philly -- talks alot of smack for a team that has won nothing.
San Fran -- Don't hate them as much now that Harbaugh is gone.
Indy -- Seems like the Packers where many fans respect them. Andrew Luck has a lot of fans who cheer for other teams (me included).
