fans who cheer for the Yankees and Lakers tend to pull for the Patriots, and in recent years, many of them have started cheering for the 49ers again (like they used to back in the '80s and early '90s).

The Cowboys haven't won anything for so long that the bandwagoners don't even know who they are any more. Most Cowboys fans I know are lifelong Cowboys fans who have stuck with them through 20 years of mediocrity.
