The combine list is out -
http://www.draftexpress.com/article/2013-NBA-Combine-Participant-List-4171/
There were 63 players invited, not including a notable injured player (Bennett) and some notable international players (Karasev, Saric, Adetiokunbo, Noguiera, Jaiteh, and Jean-Charles) who cannot attend due to obligations overseas.
With that many players on the list, that sort of paints a grim picture for the following notable prospects not invited -
Michael Snaer (a.k.a. Mr. Clutch)
Jack Cooley
Rodney Williams
Matthew Dellavedova (a.k.a Patty Mills without the hype)
D.J. Stephens
Khalif Wyatt
Elias Harris
Alex Oriakhi (This one blows my mind, not because he necessarily deserved an invite, but rather because I remember him being really young, like 14 years old or something like that, when UConn actually offered him a scholarship. I was around his age at the time, and I just remember my AAU friends telling stories about this guy and how good he was. Just goes to show you how you can't scout 14 year olds in AAU... sophomore year should probably be the acceptable cutoff for scouting, but eighth grade yields the Alex Oriakhi's of the world.)
Vander Blue and Robert Covington were also late additions after initially being left off the list.
I'm surprised that Cooley and Williams were left off, particularly because the two things that have them in or out of the draft are things that will be tested at the combine. For Cooley, his height seems to be overlisted, and his athleticism is questioned. For Williams, his athleticism could have put him firmly in the second round if he had tested well enough, which there was a good of chance of him doing. I suppose the same could be said for D.J. Stephens, but his game is a lot rawer at this point than Williams, and that's saying something.)
I also would have thought Khalif Wyatt's tournament showing would have gotten him more buzz.
