Sites like FanDuel, which pits owners against each other in single-day competitions with same-day drafts, provide the newest way to get into (and out of) managing fantasy sports teams. Here's the value proposition: You'll no longer have to wait an entire week to see if you beat your friends. These are salary-cap style games, which means you have, for example, 200,000 virtual dollars to spend on your team. Do you go with two or three stars and hope they come through with huge games while filling out your roster with part-time starters, or do you try to pick the perfect mix of average players who will get hot while they're on your squad? Either way, you know if you've won or lost by the time the day's final pitch is thrown.
