Do you have any idea where I can find free play by play data for NBA games? I would like more advanced data - event based, lineup for every play, player movement, passes per possession, shot coordinates and etc. I guess there isn't a free data but still I will try

Probably hard to find free but might ask this guy. http://apbr.org/metrics/viewtopic.php?f=2&t=9389

Or check out this pathway http://apbr.org/metrics/viewtopic.php?f=2&t=9405&sid=d6b2913791092d9ce939776fdb0bce25

pbpstats.com is a decent site for a lot of stuff. Won't have everything you're looking for, but it is free.
