I'm generally not a negative fan. It's just where I am attitudinally now. Except for the Jets, I don't get happy when things go badly for other NFL teams. In football and even in baseball, I just root for my team to take care of its business and figure if they can't, they don't deserve it. It's how I can like the Rays and the Sox. Until the head to head, I can do it.
I'll cosign with this. The only teams I actively root against are the Phillies, Cardinals, and New England Patriots.
