Rookie 3rd in backfield?

The Falcons rested RBs Cordarrelle Patterson and Damien Williams for Saturday night's preseason finale against the Titans. Rookie Tyler Allgeier opened in the backfield, with Qadree Allison and Caleb Huntley working in early. That usage makes it appear that Williams will enter the season ahead of Allgeier in line for carries. We'll see whether the rookie can work his way up. If he is 3rd at the moment, that would at least mark progress from how the preseason started. This looks like a backfield to avoid beyond Patterson for now.
