Falcons signed QB Luke McCown. McCown has three years of experience in Dirk Koetter's offense from their time together in Jacksonville. We suspect impressive rookie Dominique Davis has sewn up the No. 2 QB job, and McCown was signed for garbage-time duties in the preseason finale. The Falcons can keep McCown on speed dial if injuries strike during the season. It doesn't hurt that he brings intel from a division rival after spending training camp with the Saints.
