2013 is going to really have to dig for the depths to match the historically awful 2000 draft. Not only did the 2000 draft lack star talent, it also produced shockingly few players who were able to hang around for the long-term. Only 4 guys from that draft (Jamal Crawford, Hedo Turkoglu, Mike Miller, and DeShawn Stevenson) went on to play 800 or more games. Compare that to the 2 years before and the 2 years after: 98- 9, 99- 11, 01- 12, 02- 5 (so far, but that number will probably double next year as 5 active guys are within 60 games of reaching that mark).
Basketball Reference uses a rating called Win Shares, implementing all of a player's stats and taking into account how many games his team won, allocating parts of those wins to each individual player. The 98 draft had 7 guys top 50 for their career, 99 had 14, 01 had 13, and 02 had 7. 2000 had 4 (3 of the 4 guys who played 800 or more games, plus Michael Redd), and the guy with the highest rating was Turkoglu, who would have rated 7th in 98, 8th in 99, 8th in 2001, and 3rd in 02 (though again, some of those guys are still active, and it's likely that number drops to 5 or 6).
It's hard to find any measure in which the 2000 draft isn't at or near the absolute bottom. 2013 probably isn't going to amount to all that much compared to a normal draft, but I doubt it ends as poorly as 2000.
