Defending the Quinn hire is LAUGHABLE. Quinn is a trashbag that was carried by an MVP quarterback... right up until he wasn't. Watch that Cowboys/Packers game again Breer.
As soon as Shannahan left Quinn, the Falcons crashed back to earth. He's a decent DC, but no, he's not the coach. And the reason the hire of McDonald is better than Quinn, is because he's new blood, not a has almost been good coach...
