Well, none of this should come as a shock to you by now. From Chad Ford over on ESPN Insider:
I'm told that's it's very likely that Georgia Tech's Thaddeus Young will stay in the draft, too. His family has begun to interview agents, a sign that he's in to stay.
Initially, Young set a condition of being in the top 15 to stay in the draft, but now he's saying top 20. It's a pretty safe bet that he'll go that high. In fact, Young was one of the 15 players invited by the NBA to attend the draft and sit in the green room, which is a good indicator of where NBA teams have him ranked.
If Georgetown's Jeff Green pulls out of the draft (some GMs and scouts now think he will), then Young's stock probably rises to the point that he goes between No. 10 and No. 15.
