If he is a lock for the first round I think he's gone. They draft so much more on "upside" anymore that someone would draft him and hope he develops a consistent jump shot.
We would love for him to stay, but I can't blame him if he would leave.
I think if Royce were a bit taller and/or had zero character/behavior questions, teams would easily gamble that he can develop midrange game and free throw shooting.
I just don't see him being a first round pick when he's short for an NBA #4 and teams will see question marks about his character giving him that much money. ISU fans have embraced him and love him, but NBA teams will see a kid who got in trouble with the law, released some weird youtube videos, transferred before playing a game at Minnesota, and has an anxiety disorder.
I'm not bashing him, it seems he has overcome all that and it's awesome. But these NBA teams would be putting a lot of faith in a lot of things. It's not just about him being a top 30 player in college, it's about being a top 25 American player investment because there are a lot of near sure things in the international game now that have been tested in an environment more like pro sports.
One more successful year on and off the court could erase both or one of those areas of doubt.
