I think the Cowboys, Steelers, and Packers qualify as the Yankees much more then the Patriots. The Patriots are certainly the flavor of the decade, but I think you need to take a more historical perspective when choosing a team to compare to the Yankees. If we take the Super Bowl Era then the nod goes to the Cowboys, they have the rings, the fanbase, and are "America's Team." The Packers have the most titles of any team, but 9 came before the Super Bowl era, it's like comparing apples to oranges. Finally, I think a strong argument can be made for the Steelers, 6 Super Bowls, a heavy hall of fame lineage, and a rabid fan base, and the Rooney's most closely emulate the Steinbrenners except with a bit more class.
