The Atlanta Journal-Constitution helpfully unearthed stories on the beginning and end of Georgia Tech's 2005-2007 probation, in light of recent events. Go read them and then let's discuss. 

So, yeah, the same line that jumped out at you jumped out at me as well. It was helpfully bolded by the editor on duty, and should've been. Here it is:

If Tech commits another major infraction before Nov. 17, 2010, it will be subject to added penalties as a repeat violator.

Uh-oh. We don't yet know the timeline of the alleged violations that will be revealed this afternoon, but we do know there's a very, very slim span of time in which a violation could've occurred that wouldn't fall within that extra-probationary probationary period (the NCAA is weird). Georgia Tech fans are now in the bizarre position of hoping Paul Johnson's staff was found to have committed a NCAA violation within the past eight months.

Anything involving Demaryius Thomas or Morgan Burnett would have happened between 2006 and January 2010. According to a report by Zach Klein, those could be the players involved.
