What happened: Stefanski said Ethan Onianwa is doing a nice job after the Falcons gave him a wide range of assignments. The rookie is working through his first NFL training camp.

Why it matters: Onianwa's progress gives Atlanta another option along the offensive line. His development carries added weight as the team sorts out its preseason rotation.

What to watch: His workload in Friday's preseason opener will offer the next measure of his progress.
