They are pretty spot on after the draft or whenever they revise it. They aren't that good this far in advance. Not sure when they updated it either.
Read Hegotgame's link and you will see nbadraft.net is the second best website/author in terms of guessing where players get drafted. The loser Chad Ford who I have heard some people on here mention as a reliable source is 8th in the rankings. That speaks for itself. The website was updated today for your insight and is updated usually twice a week.
