On his "Who's in Who's Out list for underclassmen" Chad Ford lists Moe as a player who has officially declared for the draft but not yet hired an agent.
It's an INsider article but here's the gist..
IN THE DRAFT
Players who officially have declared for the 2012 NBA draft
* To preserve eligibility, player has not hired an agent
Moe Harkless, F, Fr., St. John's*
Harkless may not have been pegged as a one-and-done prospect coming out of high school, but he was among the most productive freshmen in college basketball this year. His energy level and athleticism should translate to the pros immediately. He needs a better jumper, but he's likely a mid-to-late first-round pick.
