Look at the timeline of the NCAA's investigation into Georgia Tech Yellow Jackets sports. It began in Nov. 2009, yet the first anybody heard of it was on the morning of the actual announcement. Compare that to the Ohio State, USC, Tennessee and UNC stories, which were publicized months or years in advance and saw every major milestone met with national attention.
Or the Oregon story, which has only begun being investigated. We already know several major players and the issues at hand, thanks to national and local reports.
On the Tech story, we missed the beginning of the story and pretty clear milestones like these:
For speculators on what a school or NCAA "must" release: Tech got an NOI on 9/13/10, NOA on 12/11/10, a hearing on 4/15/11. All under radar.
That's a notice of investigation and a notice of allegations. Tennessee is currently in between stages two and three on that list, for example, and think about how many stories you've already read about Tennessee's troubles.
For one thing, the priority of the Atlanta media will always be on SEC schools over ACC schools, even when we're talking about in-state institutions. That's just the way it is, based on audience interest. But various independent media outlets do cover Tech sports and Tech sports alone, and several national publications have dedicated writers who cover the entire conference.
These things just happen in a complicated sports media world, I guess. That's really the only explanation I can hurl out there as to how this story remained in the shadows for almost two years. Pretty baffling.
