There are many ways to run your baseball league if you're the commissioner. Fantasy baseball took off in popularity as the Internet became more popular, and that's no coincidence. You had to be a dedicated ultra-fan to catalog box scores every day.
There had to be a better way, and the Web came along and made everything easier. Many sites have come and gone, and two mainstream sites – Sportsline and Yahoo – are the gold standard with most of the fantasy baseball traffic these days. A look at them and several of the smaller, no-frills competitors in the business. (Note: These are not an endorsement.)
CBS Sports
It's the priciest (up $10 to $159 per league), but they've refined this site for 16 years now. (Disclosure: I've had a team on Sportsline for more than 10 years.) If you're the commissioner, essentially all you have to do is a quick setup, set your draft date (you can have a live draft over the Internet or input your teams later), conform the site to the stats you'd like to use, the format, etc., and the site takes over from there. Owners can make their own pickups and trades based on your league rules. They also tout mobile phone access and scouting tools.
You can do a lot worse, but the price tag is the highest. Sportsline also offers free leagues for those who don't have a league to join and other "premium" baseball games.Yahoo!
Yahoo has two versions of its baseball management tools. Baseball '08 (free) and Baseball Plus 08. Both services offer live drafting (super stable over the years), wireless capability and commissioner tools. But the free Yahoo service is not as customizable, and there are bells and whistles in Baseball Plus (still $124.99 for a league for the season) that aren't in the free version, such as StatTracker (live updates), a draft kit and a weekly scouting report. Those extras can be bought a la carte in a free league, but if a few owners want it, it probably would be cheaper to just pool the resources of the league and buy Baseball Plus.
They also offer a prize for your winner – either a T-shirt or commemorative bobblehead. That's a nice touch.
ESPN
ESPN is where I go to prepare for my drafts, as their tools for draft prep might be the best. They've been in the stat service biz for a while, but my experience with ESPN a few years ago wasn't great. They also had a bad meltdown in 2007, when the company had to apologize to its customers.
But the price is still right for ESPN for all of its leagues: Free.
Like Yahoo, ESPN also has a league where you can jump in and play in a standard 10-team league for no cost (either with your friends or strangers) and it uses basic stats that aren't customizable. In their custom leagues, you can do almost everything you can do in the Sportsline and Yahoo leagues.
If ESPN ever gets its act together technically, they've got a winner here for everybody.
