NFL Network featured Hall of Fame coach Don Shula on Tuesday as part of its "A Football Life" series.
Heading into that profile, the former Miami Dolphins coach told USA Today that head injuries were a concern while he was coaching. He said concussions didn't draw as much publicity, but they were just as scary to him.
Shula said there's a lot in the documentary that will be new to fans.
