Currently with data for the 2009-10 postseason, but promising to add more soon. Interesting spiced-up boxscores and play by plays with a little more information than you generally get. Looks good. They also have leader boards in some unusual categories, like jumpballs, travels and different violations (e.g. LaMarcus currently figures "high" in the dreaded 3-second violation). Though things like that will get more interesting to follow for a whole regular season once there is more data. E.g. here a boxscore for the game 4 in the Blazers-Suns series. Here is the same game on fellow promising newcomer Hoopdata as a comparison. There is finally some movement in the field of putting better data into the boxscores than just a player making a 2 point shot. We just have to learn over time what is useful, what is rather esoteric and what gets accepted by the general public.
