Sam Vecenie says he now has Castle in the top 5 of his board in this mock draft video. Good discussion of him (and some quite flattering UConn talk as well) here.
Good discussion, thanks for posting. Vecenie had Castle going #8 to Houston, but as you said, said he was in the top 5 of his own rankings. The co-cost, Bryce Simon, had Clingan going to Atlanta at #15. It sounded like he could have gone anywhere in the teens, depending on team need.
Another interesting note is that when Vecenie had Edey going to the Celtics at #30, he mentioned that he has not talked to any NBA teams who project Edey as a lottery pick, despite some recent mock drafts suggesting he could go that high. Some of the guys doing mock drafts really are a lot more plugged in than others.
