What happened: Penix called Callahan "a genius of a mind" and said the line coach runs most of the ground scheme. He also said a college rib injury was worse than his recent rib issue.

Why it matters: Atlanta's production starts up front, where the run scheme sets down-and-distance. Backing from the starting quarterback signals stability for that room entering the next game week.

What to watch: The coming week will show how much Atlanta leans on the ground scheme.
