I offer up a weekly printable office football pool sheet for the NFL season. I've had it running for a few years now, and I find that it ends up doing better each year. It's mostly automated/passive, but I spend about 15 minutes each Monday night updating it for the next week. I mention this one because it's one of those things that I just did, mainly for my own needs, and put out there. And it mainly just sits there but does better year-over-year.
