According to this Reddit thread, Chad Ford's NBA draft rankings in recent years have been changed after the fact to make the rankings seem more favorable based on actual NBA performance of the draftees.
Looks like Chad Ford changes his draft boards after the fact to make himself look better. Take the 2013 draft board for instance.
Here's a cache of the page a month after the draft: https://web.archive.org/web/20130729144022/http://insider.espn.go.com/nbadraft/results/top100/_/year/2013
And here it is now: http://insider.espn.go.com/nbadraft/results/top100/_/year/2013/
Notice how he's raised players that have done well (Antetokounmpo, Carter-Williams, Hardaway Jr., Dieng, Gobert) and dropped those who haven't done so well (Karasev, Larkin, Jamaal Franklin).
Kinda shady I think.
After this story got a bit of play, ESPN reverted Chad Ford's rankings back to their original state. Ford claims he didn't make the alterations, and ESPN issued a statement saying they believe him. My guess: some poor, blameless CMS will take the brunt of the scapegoating.
Given enough eyeballs, all ex post facto malarkey is shallow.
