ESPN's Chad Ford has this to say about Clark:

Earl Clark, F, Jr., Louisville
Clark hasn't made an official announcement, but NBA agent Dan Fegan confirmed to ESPN.com on Saturday that he has signed Clark as a client, ending Clark's eligibility. Clark is one of the most versatile players in the country. His skill-to-size ratio is off the charts. However, he still lacks a consistent perimeter shot. He reminds some scouts of Julian Wright. He has top-five talent, but his inconsistency and concerns about his work ethic could cause him to slide into the late lottery or mid-first round.

I was really surprised the statement "top five talent". I never really saw it with him. Anyhow, in other shocking news, I'm no NBA scout.
