Yahoo! Fantasy Baseball got a nice upgrade this year. The things I’m particularly enjoying so far:
A Roto-League Standings Visualization
Brilliant! 
A great way to see where you are in your league, and particularly what areas you need to make a move in.
Improved Offline Draft Submission
My keeper league does an offline draft every year. In the past, it’s been several hours of agony entering the results for each team. This year, that all changed. They have a slick little auto-complete widget (probably using the same Y! UI library I do in PHP Tag Engine) that made it quick and easy to enter in all of the draft results.
Drag and Drop Roster Management
Now when you make a bunch of position changes, you don’t have to worry about leaving two players in your first base slot, etc.
Thanks for the great improvements, Yahoo!
Now about getting some RSS feeds for league activity…

The last item, the Drag and Drop Roster Management is the key for me, makes the whole experience much, much easier. I like how it highlights for your where you are allowed to move players. Very well done Yahoo.

Alex, where is the Roto-League standings visualization at? I can’t seem to find it anywhere.
