It's hard to draw comparisons. Easier to class the organizations and let you sort it out.
Cowboys -- prima donna organization top down with some real talent in their history and across the nation the most popular team. Always on TV. Won a few times also. Glass jaw QB replaced with new guy who might actually be the stuff. Placeholding slip by glass jaw QB kills last real playoff hopes. = Kopites (you got that right)
Steelers -- down to earth organization with good owners and leadership up top. 3 coaches (managers) over 40 (?) years. Won 6 times. Play very predictable, smash mouth football. Very likable (if you're not a Browns/Bengals/Ravens/Eagles guy or an envious Kopite). = ? Juve? The team Arsenal wants to be?
Patriots -- laughable franchise for almost their entire history. Cinderella run in 1985 decimated by the Chicago Bears, with signature move the
goal line rush by Refrigerator Perry. Hard luck team until they found two important pieces, each of who may be the greatest at their job in NFL history. = United or Chelsea?, but only if football was created in 1992.
Packers, Chiefs -- midwestern/small-market clubs with great history and some of the best support and home atmosphere. Major difference is success: Packers 4, Chiefs 1 title. = Villa, Everton, or Geordies?
Seattle -- the cheese boy described them well. = City?
Texans -- new club with limited success and little offensive talent. No threat in this playoffs, but could be good later with the right organization. = MK Dons organization with Bournemouth aspirations?
Falcons -- terrible club in a bad sports city. = Fulham if they didn't have Craven Cottage.
