He's an interesting talent but I didn't think he was a top end point guard. He's not quick enough for that role and he is not a particularly good perimeter shooter. I wish him well but my guess he ends up playing overseas.
He's not going anywhere -- he wants to know from the pros what he needs to work on. This is good for him to let teams know that he thinks he is good enough, and get a free analysis from the league. Fred probably encouraged him if he mentioned it -- its going to be a cold bucket of water and good motivation to go to work if no team is interested in him.
My opinion is that he won't start for Nebraska this year -- he's behind Trey M and probably Webster. If he works on his handle and his scoring, he might be able to make a NBA team as a change-of-pace guard and fill-in-forward. He looks like he's headed to Europe to me as of now.
