Why are so many people surprised that there's more Pats fans now? The biggest sports nuts are often kids. For anyone born after, I don't know, 1985 (10 yrs old in 95), the Pats have almost always been good. So a 10 year old gets on board with Parcells, etc. That kid is now 32 years old...he's been a Pats fan for 20+ years! Most don't even know the old Pat Patriot unis. Kids root for winners and for who their friends root for (if their parents don't influence them), and it snowballs from there.
And often times, parents become fans along with kids, because of their excitement. Ask someone who's 25-30 years old if their were Pats fans around as kids.
This is perfectly normal. We are talking about 22 years of success. Not to mention the Pats being OK before that, going to the Superbowl in 1985. The problem is, most of you are getting over the hill.
