Military family, so we moved a lot. Never lived anywhere with a home team before.
I originally followed the Cowboys, because they were my dad's team, and Dallas ruled the Arizona airways in the 60s and 70s. We lived in Texas when I first started really following the NFL, during the Staubach/Dorsett Cowboy years, so it was an easy hook.
Moved middle of my 5th grade year, and had a friend that was a huge Dolphin fan. They had a satellite dish and got most of the Miami games on. It was a huge family affair for them, and they let me spend most of my Sundays at their house watching the games with them. Somehow, I started following the Dolphins until I graduated HS and moved back to Arizona (ASU).
Decided I needed a west coast team, and that was Bozworth's rookie season. So, I dropped the Dolphins and started following the Seahawks, 'cause they were young, and I didn't want to be a front-runner 49ers fan. Of course, the Cardinals came to Arizona the following year. I intended to stay with the Seahawks as they had made the play-offs, and had some entertaining players (Boz, Largent, the other Curt Warner)...
Of course, as a new team to the valley, I watched most of the Cardinal games that inaugural season. The come-back win over the 49ers was just a classic football game, and was when I finally said screw the Seahawks.... I'm a Cardinal fan. Followed it up with my first live game the next week, against the Giants, another win.
I wavered once... Living on the East Coast with the expansion Panthers. Buddy Ryan was running the show in Arizona, and I couldn't stand him. Once the season got going though, coupled with the rise of the internet and being able to follow my Cards across the country, I've been loyal ever since.
Go Cards!!!
