That's because we're Saints fans and we stick to one team. I've met a lot of people here in Texas that have five other teams they pull for when they disown the Cowgirls after three consecutive losses. I'm sure people do the same in other large market cities.
As far as leaving well enough alone, it's a great idea. I actually think it's the best idea, but it won't happen. You don't get to be wealthy enough to own a football team because you know how to leave well enough alone.
It's all about the next billion dollars for those type of people.
