Who is the Biggest Project?

JSM or anyone else who is knowledgeable,
I heard the Lakers dont want any picks this year. Assuming we do have to pick, who is the biggest project available that we might draft then put away for 2-3 years. I heard Nick Calathes could be drafted even though he will be playing in Greece for 2 years therefore I think he is a good candidate for the Lakers to take in the first round.

If anyone is aware of big time projects in this years draft who may be available when the Lakers pick please post because I think this is the direction the Lakers are looking to go in unless something drops into our lap.
