I don't know how many people actually read the blog this time of year, what with the NFL off-season and NCAA quieting down, but this is from AOL Fanhouse:
Tyler Hansbrough to enter NBA Draft
He's apparently not going to hire an agent, so he could come back, but just wants to go to the camps and see if he can help his draft stock any. I'd say now (per DraftExpress and NBADraft.net) that he's in the mid-20's. I'd guess that if he plays his way into the lottery, he'd stay, but anything short of that he'll return as he could just go pro as a senior with the same results. This is easily the smart move, since you can "test the waters" once and come back, and he isn't testing the waters next year, its for real. Also, apparently Lawson is coming back as well. He's got a similar draft position to Tyler's, around 20, and has a myriad of PGs ahead of him. If he doesn't play any better next year he'll improve his stock just by the lack of PG's in the draft.
Projected UNC Lineup:
PF Stepheson (Hansbrough?)
Bench: G Bobby Frasor, G Larry Drew, G Will Graves, F Danny Green, F Tyler Zeller, F Ed Davis
