Then again...I imagine fantasy football would be a lot slower paced than fantasy baseball...exactly opposite their real-life counterparts!! Each NFL team only plays once a week, so I imagine you have a little time to think out moves and such. Baseball teams play almost every day, so in fantasy baseball it's a daily committment to make sure that that I've got, for instance, starting pitchers in pitching slots on the day they pitch and not on the bench; watching righty-lefty matchups; paying attention to who is likely to be played and not (for instance, for the last few years fantasy baseball players have needed to know that Barry Bonds is probably not going to play a day game following a night game.).
I might be interested in a fantasy football league.
