A significant portion of the Falcons' fan base is comprised of Georgia fans. How exactly do we think that Georgia fans would react to losing their now-beloved defensive coordinator to the local pro football collective right before a season in which Georgia will be preseason top ten and expected to win the East and challenge for the SEC title? Arthur Blank didn't get to where he is by angering his customers. It would make a lot more sense for him to back the Brinks truck up to Steve Spagnuolo's house so the Falcons can sell their fans on the fact that they hired a Super Bowl-winning defensive coordinator.So no, I don't think that this is happening. In fact, I seriously doubt that the Falcons even considered it beyond "yeah, that would be a terrible idea."
If the Falcons wanted to do a change of scheme, how about the Air Raid? It's almost certainly too radical for a winning team, but if some teams are going to move towards the spread 'n' shred, then why wouldn't someone try the other offense that is ripping up college football? It's not like the run 'n' shoot was a resounding failure in the NFL.
