NBA All Stats
Gorgeous One Pager dedicated to providing stats for the NBA since 1970. The detail in these infographics is as good as it gets, not to mention the beautiful CSS transitions to switch between them. A seriously amount of love has gone into this site and love is what it deserves.
This website has unfortunately been redesigned or gone offline, so I have removed the direct link to it. The screenshot below hopefully preserved enough of the design but if you are really keen to inspect further, try this Archive.org link. FYI: the site was first featured on 04 November 2013.
