I doubt there's anything to this, but I thought it was interesting that Robert Johnson re-tweeted Ed Davis' comment about Johnson potentially picking UNC this Friday:
Ed Davis @eddavis32
Carolina??RT @robjohnson4_: My school thought it would be best to switch my annoucement earlier. So it will be at 3:30 in school library
Johnson attends Benedictine HS in Richmond, the same school Davis attended before coming to North Carolina.
