I was sweating on how low a couple of those snaps were, but it's an all-too-common tale that a QB and backup center(s!) are out of sync, and it results in fumbles and turnovers. Conceded, a lot of that phenomenon is when a QB is under center, but still. The team didn't panic with a loss of O-linemen, and Retzlaff stayed focused on ball security through each snap.
I sure like this team not putting the ball on the ground.
