The deadline for deciding on entering the draft, and so far, no one from UNC has ruled it out. No one means Tyler Hansbrough, Ty Lawson, Wayne Ellington, and according to some reports, Danny Green.
We're reading between the lines a bit since there's been no formal announcement, but we'd expect Hansbrough to put his name in and explore his status without an agent. This is what Dick Baddour seems to expect.
The others? Well, no one has said no yet, so you have to think there is still some level of interest.
