Lot of the new HC hires coming in from an offense background, good DCs are going to be at a premium to provide them with support and expertise.
First steps taken to provide a new home for the Falcons, planned to be complete for the start of the 2017 season. The Georgia Dome will be 25 years old by that point, which is about the average lifespan of a domed NFL stadium.
New home will still be in downtown Atlanta, and will hopefully help the city keep those events that currently use the Dome. Long as it doesn't end up being called "Home Depot Stadium" or something similar, it's all good.
